The last shop did NOT build this 327 for BURNOUTS!

okay we've got the cleaning guy here what do you got well we've got a uh 327 here that the younger brother of a good friend of mine from when we were virtually kids starting out together Mikey is the Fell's name that I worked with in the machine shop as we as kids kind of learning the business he went on to become a truck mechanic and of course I stayed with it anyway his younger brother called me up said hey I've got a 327 here in my truck that I wonder if you can go through for us story goes as this engine has been done sometime before as I look it over here I looked at the casting number it's uh 3858174 which is a 327 small Journal engine casting date on here k45 so it was cast late in 1965. I would have guessed this would have come out in 1966 model but he told me that it's either a 67 or he's got it in a 67 truck right now Story Goes he was somewhere went to a burnout competition and he got a little bit carried away a little higher RPM than he thought and hurt the engine he thinks it has a broken piston maybe a broken piston skirt in it we don't know for sure looking on the back here is some of the things I'm observing the original Breather System here has been plugged off and they've evidently put breathers in these aftermarket valve covers with a more modern PVC system they've probably got it installed in something that they used the long water pump on because they drilled this hole here to be able to mount the alternator up here which is not a real good idea because the heads that are designed for this this casting comes all the way up here fills in just a little bit more and actually has a it's cast in there so you can have a bolt hole this one with the way that's done when you drill that hole it goes through to the inside of the motor as you can see we've got an oil leak here because of that but I I don't like it when they do that but sometimes you got to do what you can do it's been changed over to a Edelbrock air gap performer intake manifold this probably originally was a 275 horse 327 with a Quadrajet Carburetor four barrel manifold on it but one thing it really concerns me is I notice on the back end of it here somebody Pryor has had some issues getting the galley plugs out of this and something has been broken here and braised back up and it is quite wet up here in the back end I'm a little bit concerned wondering if we have a leak in that repair so we're going to look at that real close as we get into it here but other than that let's start taking it apart and see what we find but it's not a catastrophic failure but he does think it has a no my my understanding is the engine was still running he said he drove it home after this burnout competition and I think he said they dropped the pan on it and found parts of a piston or what he thought was a piston so we'll we'll find out here real shortly [Music] [Music] the plan is build it right right yeah he wants to put back right again make it as good as we can [Music] I hope we don't get in here and find out it's already been bored to the max or something throw that thermostat away never put an old thermostat back in a motor you never know what kind of shape they're in I'm gonna get a wobble socket uh that oil shiny huh you know when you're tearing down the engine that's where you don't want things to be too shiny hmm make sure it work for that you just can't wait to clean all this can you I can't it's my favorite thing heads off yeah wow yeah that's weird that some of the bolts came out real real easy some of them quite a bit harder and then we get down to the center bolt on each head and to get the half inch gun what's the casting date on your head k25 this one is k35 and the block is k45 this is probably all original parts that went together because they are all cast very similar time over there foreign s off we set them aside we'll tear them down here a little bit later and look at them but anyway I pulled both head gaskets off to kind of look at them and you can see here the areas in between everything is nice clean there's no dark area between where it's been blowing any compression across so it appears the head gaskets were were sealed very well in spite of what it felt like when we took those bolts out so I don't think there was any issue with head gaskets leaking or anything on it I'm looking at the Pistons here see if you can get a shot at the top of those see how that's all washed clean on the outside edges there this one back here is really washed clean I would say that's been using quite a little oil that's an indication that the oil coming up past the Rings and washing the carbon off on top of the Pistons just to feel The Ridge at the top of the cylinder here it does not appear to have anywhere unless somebody has cut the ridge out of it and just re-rung the block at some point in time but when you get back to this cylinder here I'm looking how aggressive the hone marks are in this cylinder I'm not impressed with what I'm seeing there on on the home job in fact I still feel it that's that's quite rough I'm sure that's why uh why we're seeing the oil consumption on that now that that one is really rough even after this has been run and it's like I can almost catch my finger in the in the crosshatch well it's not much of a cross head no it's it's just kind of a circular motion there but it's for some reason it's quite rough maybe let's go ahead and pull the lifters up out of here or get them out of the way whether the cam is good or bad we're going to replace it it won't be putting the old one back in so I'm not going to keep track of where any of these lifters came from it's certainly not wiped out yeah there's something going on in the bottom side some of those lifters but they were all everything looks like it's rotating huh you just want to wait till we yeah I'm gonna wait I don't want to force that passed and mess the block up is it just two or just two of them there so we just hauled scrap this morning how about we start making some more sounds good start with this right here good place for those I hope we didn't throw away any customers work it's one way to get out of work they don't have any proof they brought it to us 60. are you serious yeah it's 60. already 60 over now between that and this uh that defect we found on the back of that block we may be uh having to scratch this and start over or something else can I throw the gaskets away yes my words didn't come out there can I throw the gaskets away is that kind of like your 30 tooths yeah 25 30 tooths it's always good to keep the internet guessing on whether you're trolling them or whether you're that dumb so do we know if this has any oil left in it or I don't think we know I'm gonna say you drain the oil yep he drained the oil good but I'm still gonna let's drop the pan without turning the engine over that way if there's any residual oil in it it doesn't end up in the top as we roll it okay I got this lifter out kind of looks just just a little varnish on the bottom of it so it was holding it if we don't take these washers off they end up getting lost out in a Steel abrader I think he had had the pan off just before he brought the motor to us but I wasn't sure yeah just a little bit of residual oil in the pan no chunks or anything no chunks but uh yeah I'm sure they took the chunks out when they dropped this pan I always like to take that nylon washer off the drain plug before we put things in to bake because that nylon just melts and gets all over the place kind of makes a mess timing chain has been replaced but it's just a stock replacement I would have thought they'd put maybe a double roller in it but they didn't we usually do double roller on everything pretty much yeah since we're replacing cam bearings and the cam I'm not worried about digging up bearing so I'm just going to kind of drag that out Comp Cams 12 242-2 did it do it yeah which way you want to go my way or your way towards you okay go easy yeah go ahead and I'll try to catch what's on this side where's uh crab time Pig mats yeah we've got some there that are getting kind of dirty it's time to use them on something and then throw them away we're really stingy with these hey they're those are so neat you got a broken skirt here oh we sure do man the whole thing is gone well again that's on uh one of those cylinders that looked like it was using some oil so I guess it has a good excuse from your sister Lunch is ready and I don't know about you but I'm not going to pass up lunch we're back from lunch now before lunch there as we was kind of tearing us down and you pull the timing set off you pulled this gear part way out or bottom sprocket part way out and I knew that was not good because it was supposed to be pressed on but what I did not realize that this was one of the very first variable timing variable camshaft tiny engines that Chevrolet designed clear back in the 60s and you folks all thought that was new but this one uh this is not good and as we pull it back here get it just ready it'll come back uh I don't know if you can show that right now but the it's the key slot in the sprocket and the key is just about completely worn off it's a wonder he had not lost yeah so pull it back out real quick yeah there's like barely any key left there see this is a early engine if you look here there's there's no bolt in the front of the crank here to hold the harmonic balancer on you just press it on tight but with that being said there's also nothing to hold that sprocket up tight so it has to totally depend on the The Press fit and for whatever reason this has lost the Press fit and has been working on there uh so most most likely uh the crankshaft will not be any good without a whole bunch of work here welding the snout up and turning that back down and it's probably just not cost effective to do that look at this key yeah see if you can get close up of what's left of that key yeah I mean everything about that the key for the balancer is almost gone and then the little Half Moon Key here and this area back here where the sprocket goes on has just about completely worn that off and again it's not only just the key but you can feel a pretty good lip here on the side where it's worn into the crankshaft so there's no more press fit yeah so that crankshaft seen better days I mean we could fix that if we had to but those cranks are not that hard to come by yet but what we can replace that one it looks like it's pretty much just a boomstock 327 with a cam bearings are looking pretty rough 10 under so it hasn't been ground down all that far doesn't look like the rods were ever reconditioned they still look original got it yep what does it look like casts stock cast Pistons something 10 AP 310 would that be a federal model Federal mobile that's the number yeah I don't think has much run time on it yeah these cast replacement pistons for 327 I guess they're okay for bone stock motor but they don't seem like they're actually that good of piston not for Burnout competition not competition okay the same ready yep foreign you suppose that piece just fell right clean through and right to the pan it appears so uh I don't see any anything else in here there's no uh no damage no nothing beat up anywhere uh I'm guessing that just came off and went straight to the pan and probably can't waste time putting the bolt boots on there when we don't think we're going to be using that crank and it certainly needs ground anyway but but if we don't put those on there'll be somebody telling us we should have so yeah there's nothing uh you know there's some scratches on the skirts there but nothing of interest can you see this oh we got some four corner scuffing going on is that the broken one yeah that's the broken one I wonder if that one uh got hot and actually tried to tie up a little bit in the cylinder before it let go okay now this is that cylinder that looked a little bit funny yeah on the cylinder wall and the crosshatch or rough rough hone job looks like he's using some oil yeah show the carbon on top of that one or lack of carbon how's the oil ring look is a nothing wrong with the way the ring is on there is there now just the two scrapers are lined yeah but that's that's not good but that's not what's causing that problem I know today I'm lined up on all the Pistons yeah whoever put this together lined up the Gap and in all the scrapers yeah every one of them yeah wow I can't believe anybody would actually do that did they just not have near enough oh wow uh that's from some well look at the cylinder next to it yeah when they board that block they board it way too close yeah yeah uh they didn't leave enough material in there to even hone out and when you see that at the bottom like that I can see it on these cylinders too they probably had a pretty worn out old boring bar that is the um as it got further yeah as it got farther out it started having more and more uh wobble wobble to it yeah and wobbled out the bottom of the cylinders there and then they had nothing left to hone out of it you can see on every oh we didn't I thought we were done a pistol we got two more to go here yeah I can see all the comments about how pathetic it is that it takes two people to tear down an engine well you know when you get to be my age why you need all the help you can get especially when you've only had 40 years of training that's right uh potential spam do you know anybody by that name no I'm getting passed on that call yeah again in gaps all but lined up a little bit scuffing on that very much budget build other than at some point in time the crankshaft have been ground 10 under on the rods there anyway we'll see what the mains are block 60 over so it's about to the max there I was watching somebody else's tear down video or the weekend and I don't know what kind of impact they had or if it was just the way they were speeding up the uh sound on it but it sounded like some kind of Star Wars gun just so this thing has an adapter on here to change it from the canister filter back to a spin-on filter I have never seen one that style does that have a brand on it says made in USA PC hmm normally I don't like those things because I've had too many of them that seem like they always leak and I felt like they probably bypassed more of the oil than they actually filtered but that one in there actually has a gasket down here in the bottom and the gasket around the top here looks like a pretty good setup so the crankshaft is 10 under and on Mains also date on the bearing is the first month of 19. so this can't it hasn't been that long since this engine was done yeah same way on the rod bearing it stated uh third month of 19. so yeah this has not been together that long Mains look better than Nia rods do if I cheat and take it over to the side I can that's what we were talking about you can see the spiral from when it was bored that left I mean you can feel that with your fingernail yeah yeah no no hone marks there and it's like that on I think every cylinder yeah it is on this side so normally at this point we'd go ahead and get the freeze plugs and cam bearings out take all the galley plugs out uh but considering this Block's already 60 over it has an issue with that Galley plug on the back where it's been brazed up again um I'm not sure anybody's ever going to do anything with this block but you know what we ought to do let's run gauge through it and see just what the bore does look like okay I set up this gauge for sixty thousandths oversize wow down there in the bottom we're two thousandths tight wow there is uh ten thousandths different I'm gonna go check my gauge again I can't believe it's that far off I go to the bottom of the cylinder and measure we are actually more than two thousandths of an inch too tight and as I come up it's like a big funnel just tapered yeah when I get to the top here I'm six actually sixty six thousandths 4.066 should be 4.060 now one and a half tight by time I get to the top I'm more than 10 wow and you're now you're on a cylinder that was broke uh yeah this is the one that was broken so two thousands tight in the bottom get up here at the top I'm six thousandths big again about one tight in the bottom holy crap more than 10 big at the top thousands tight five big about one tight five big two thousandths tight five big two thousands tight four big I'm not sure what went on with this block well it's not worn ten thousands well not at this point unless it was worn ten thousandths at some point in time and then somebody cut the ridge out of it and then honed it to the point where you can't feel the ridge in it any longer it's almost like somebody honed it that way it's hard for me to Fathom how they could even hone it and make it come out that way whatever they did is so coarse here at the top you can actually catch even with the glove on here as I run my fingernail up and down that I can catch my fingernail with the glove on in the little uh grooves from the home job let's quit on this part of it for right now I don't want to waste any more time on this because I Alexa I don't want to waste any more time on this block because I don't think we're going to be doing anything with it but let's go ahead and go over there and tear the heads down and see what we've got to work with there before we put valves out here or take the valves out I wanted to look at it here uh looks like they sit up okay the exhausts seem to be sitting up real nice the intakes are above flush anyway um not terrible bad on that head this one here as we go through kind of looking at the same thing we get down here to this end that valve's sitting flush they're probably to the point when we do them again they're going to need intake valve seats in and they should have exhaust seats in set them up for unleaded if they are not already that way but I suspect they probably have hard seats already put in on the exhaust site oh we got a broken uh uh damper on one of the springs a couple of the springs we'll have to look see what that cam is it may be bigger than we think and I don't know if those Springs or anything special at all they have had new guides put in somebody spent a bunch of money on that but they didn't last now one thing that we have been doing um on heads like this originally all this has for valve stem seals is this little o-ring that goes in this second groove on the valve stem and it seals the retainer so it has to shed the oil off to the sides and then all the valve gets is just a little bit of Splash now and then we have found that we have better luck with guides when we put in uh positive seals so if we end up doing these heads we will go back with positive seals you can see the wear here from those dampers on the springs that were broken that's probably where that metal came from that I saw in the corners of the head foreign I think we probably have a good pair of castings there to work with somebody has put exhaust seats in it up get updated them for unleaded gas but at this point they're going to probably need the intake seats put in also we'll go ahead and replace the exhausts if we do them and then put on positive valve stem seals I think could probably make pretty decent set of heads out of those again so anyway uh with what we found here I think I'm going to work up an estimate for the customer unless he has another 327 to start with personally I would probably build a 350 for him because he's going to have to have a block and crank and then if he wants to put a little hotter cam in it and his manifold and stuff on there I think could make a pretty sweet running engine so I'll go give him a call now and see if we can find out a little more of the story and go from there okay
