427 cubic inches of Naturally Aspirated HP for Javelin Trans Am Tribute Build - Engine Power S7, E5

it's probably safe to say that the AMC Javelin is unappreciated but it's also a lot of fun today on engine power the guys from Detroit muscle gave us the chance to give this javelin more power and we think they're gonna like what we've done [Music] here at the powernation shops vehicles come and go there are all types of them - from side by sides to get played with in the dirt - old muscle cars that burn up the asphalt I can't forget about the truck tech guys either with their diesel Street rigs gas Street rigs even jeeps that hit the trail in awesome fashion the moral of the story here is we always have something going on if you like to go fast or modify your ride a few weeks ago mark and Tommy from Detroit muscle rolled in here with a car that has a tight group niche following and the plans that they have for it will interest you no matter if you're a Ford Chevy or a Dodge guy it can be a bit of an eyesore for some but a sparkling jewel for the next and the company has a rich history racing in the Trans Am series where they proved they could be a top contender this is the 1973 AMC Javelin second-generation generation 2 was redesigned it had a slightly longer wheelbase was wider and the designers incorporated an integral roof spoiler and sculpted fender bulges it rolled off the assembly line with a few extra pounds and the new design was said to give the car individuality even at the risk of scaring people off options were plentiful for this model several engines were available from with 232 cubic ditch inline six to a 304 cubic inch v8 and if that wasn't enough how about a 360 inch or even AMC's famed 6.6 liter 401 alright guys like we've said this is a car you either love or you hate it's really hard to be in the middle and you know find anything there why did you pick this car well we wanted to be a little bit different and well really with buying this thing we're a lot different yeah you got to say this is one of those cars it's very polarizing there aren't that many people that are into AMC's but the people who are into them are completely into them and I gotta tell you this is not a car that I love or hate there's things about it I love and then there's things about it I hate now with a build like this there's not a lot of aftermarket support so what are your plans well I'd like to see some pretty big power under the hood now we all know that the motor that's in there's you know there's really nothing wrong with it but in all reality you can make a lot more power a lot more kind of efficient wise and cheaper with going something a little more modern well it's not that hard to do because there's plenty of choices and there are a few obvious choices and I think we got something that perhaps we could use that that's just kind of sitting in the wings right now and I think that would be a good fit for this there's a couple of them sitting in there the thing is is what's the premise of the car what do you guys how much for Howard do you want yeah we'll start there I'm thinking 600 horse ok maybe a little more okay well and it's a car it's a drag car what are you doing with it no I think more of a road race car think like period-correct Trans Am somehow going back to the history of it I like it okay I like it so maybe like 9,000 rpm redline I mean 8500 that's not out of the question we can bargain a little bit yeah now this is a special edition car buy the little badge on the fender tell me a little bit about it and we'll let you carry that one because I know you're such a fan okay well I mean it's a pierre cardin edition and you know who he is if you don't know who he is he's a fashion designer an artist whew well but very it's very period unique yes like very 70s so I mean if we could carry that on to the rest of the bill that would be awesome but just the fact that it has the the correct interior some of the correct interior still in it just makes it kind of unique I'll be honest with you I I dig it man and because of uniqueness and I think what you're gonna do to it it's gonna be awesome a couple more questions I have for you with the Trans Am thoughts going on in my head obviously some wicked suspension are you guys gonna keep an automatic in it are you going manual where we thinking it alright awesome stage mmm that's in the air stuff yeah okay you can build a track car but it's also handy to have one that you can drive on the street and sometimes a cage kind of gets in the way and really shouldn't be in a street car now I agree with that street friendly is where probably it will see the most duty so absolutely yeah this is more of a tribute not an actual purpose-built track cars everywhere no exhaust and so so the thing with you know having the tribute for the you know the late 60s early 70s Trans Am car are we going to get any modern with it that's kind of like with it in all reality perfect scenario will be fancy suspension big brakes big wheels and tires late-model injection late-model power overdrive transmission something get pretty rowdy in we got it about there before we figure out what engines going in there will you guys already know why don't you see what the engine under the hood now will do see if it'll go do a Burnout right now with one of you guys okay the first question will it start no hook the battery charger up it's got a bad battery in it I'm gonna give her the raspberries [Music] a bad battery why don't you leave the keys in it Wow that's double theft protection alright here we go the best thing it happens somebody steals turn the timer there we go you see that it was the one tire fryer and it did it the rear end is gonna fall out it didn't like it but it did it will even run on some thing our guys some AMC owe me that was some dukes of hazzard looking sapphire ever seen it that was awesome oh that's so cool [Music] save some for the rest of us that's cool [Music] yes I love this job up next the javelin gets 427 cubic inches of naturally aspirated horsepower not installing your distributor correctly can lead to a lot of problems here's the right way in today's tech tip the correct way to install a distributor is first remove the number one plug and then place your finger over the hole rotate the engine until you feel air pushing your finger off the spark plug hole then look at the balancer and watch for the top dead center mark coming up on the timing pointer place the mark slightly before the pointer this ensures you're on a compression stroke and not on a split overlap wherever you have decided number one is on your cap mark the location on both the cap and distributor housing with the gear lubricated drop the distributor in so that the rotor points at the position you have mark make sure the distributor is fully seated in the block by turning the engine over until it indexes the gear is engaged in both the camshaft and all pump drive so turning the engine over is not an issue now you can run your plug wires start your engine and set the timing when you work with someone on a daily basis and get along you start to notice making the same decisions and thinking a light comes natural so when Mark said he needed a bullet that made at least 600 horsepower and ribbed to the moon Pat and I had the same thing in mind now a high-revving engine like this needs to have excellent hardware from the rotating assembly all the way up to the valve train the oiling system has to be scienced out so it avoids cavitation and starvation which means it needs a good oil pan also the induction is super critical the cylinder heads and intake manifold have to flow enough CFM to optimize a combination back to what Mike was saying about thinking alike we knew we had one engine in the building that met every requirement that was mentioned and it is our 427 inch LM e LS X now do we think this will be the perfect Trans Am tribute engine and will definitely meet mark 600 horsepower requirement originally this engine was dressed out with an 86 millimeter precision turbo and a big air-to-air intercooler it had a Holley EFI system that turbo God Kenny dot while it used to tune the engine it made north of 1200 horsepower on low boost and it was installed in our rolling dyno we called the Tesla you may be saying that engine was specifically built for a turbocharger and you are 100% correct that's why we're going to disassemble it check all the bearing surfaces clean everything and see if there's anything we can do to optimize the naturally aspirated capabilities of this awesome little engine and we think we can do it as we pull this engine apart you're gonna see the quality of the parts that LMU uses in all of their bills now keep in mind this engine was purpose-built to handle over 2,000 horsepower so we feel it'll make a great eight thousand rpm plus combo as well naturally aspirated it's tempting to rip through the teardown but if you take your time and take a close look at the condition of the parts as you go it can save you time and trouble in the end come here and take a look everything looks pretty good the bore looks good top of the piston looks fine yeah most that will wipe right off I mean the piston looks really really nice these are super heavy-duty these things are designed to make 2,000 horsepower so [Music] it's important to put each individual parts back in its original location these parts have established a wear pattern based on how they interact with the parts around them keeping everything in order will help decrease further wear and tear main bearings aren't going to be a problem I can tell you that right now no no this beautiful you always get to look like the tough guy I am a tough guy well the tear down is complete and the block is ready to go in the cleaner and you might notice we have everything laid out pretty nice man I am really stoked at how well all these parts look not surprised because of where it came from but it's gonna be awesome to be able to put this engine right back together using all the same parts right and that's why we tore it apart and laid it all out because when you were very carefully tear something apart and lay it out all in order I don't care how it is as long as you can see how everything came apart at any point you can catch something that's wrong this is the time to do it now if this came apart nothing is wrong with it at all and pretty what we're gonna use 99% of this stuff over again now obviously we're not going to put each part in the washer individually so we are then a bundle some stuff I'll get the engraver we'll make some markings on everything so we know what cylinder number and that it goes in and get it cleaned up for assembly all I can say is let's get started like we used an engraver to mark everything never use a hammer and punch it's too rough on parts our jet washer does a thorough job of removing dirt and oil using a combination of biodegradable detergent and 150 degree water the CRC smart washer it uses microbes to break down oil grease and carbon deposits without using our solvents it makes quick work of cleaning parts coming up the javelins power plant gets rebuilt from the block up welcome back to engine power we're rebuilding a 427 cubic inch LSX that's going into Detroit muscles AMC Javelin Trans Am tribute car the main bearings are going back into the saddles the way they were originally installed they have to go back like this due to the conform ability of the housing Permatex ultra slick assembly Lube is covering the bearings for the utmost protection during initial fire up this Kali's Magnum eight counterweight crankshaft was fully blueprinted by LME and as the backbone strength of a build like this the billet main caps were thoroughly cleaned along with ARP studs new ultra torque was applied to the nuts and they were ran down until they barely made contact with the caps [Music] now they are final torque the 60 pound feet on the inners and 50 pound feet on the outers the side fasteners are torqued to 30 pound feet a bump stick or custom billet cam is being reused it's a solid roller duration at 50 thousandths is 249 on the intake and the exhaust is 255 degrees lift is 715 on the intake and exhaust valves and the lobe separation angle is a hundred and 16 degrees with the timing set on we are ready to drop in the piston and rod assemblies the rods are Kali's enforcers connected to custom diamond forged pistons a couple of spacers on each studs will give the rotating assembly the room it needs to stay contact free from the windage tray the oil pump was disassembled for cleaning I always use blue Permatex thread Locker when reassembling [Music] a factory oil pickup is installed and the camshaft is degree an alignment sleeve is used to center the timing cover to avoid premature seal failure from the balancer at the back of the engine this dumbbell is installed in the oil gallery without if the engine will not have oil pressure the oil pan speaks for itself [Music] with the gasket and the head sat on the deck it is time to install the head studs using this new tool from ARP it simplifies installing the studs in tight places and eliminates the chance of aluminum from the head getting caught in the threads [Music] we taught the heads in three stages 30 pound-feet 60 then the final of 95 the valvetrain is the last thing to go together internally this is a shaft design that will withstand high spring pressures and rpms alright Pat our manifold of choice may not be theirs well I think I like this a little bit better because you're looking for something that fits under the hood so the way they're gonna see it and say hey that's not the right one that's gonna be pretty fun we won we got to run it and it's it's it's nice and easy to get it rigged up with this on the dyno and then when they get in the car they can run their other manifold because they got to hook up their injection Jackson it yeah everything and you know what I think at the end of the day we give them the billet manifold anyways they'll be happy but we'll take this one back next exceeding our expectations in the dyno cell I did it now we're under the Dino section and for the carburation yes the I said carburetor we put on a 1050 Dominator it makes it easy for us to make sure it runs and doesn't leak and the injection system will be in on the car with the other manifold we couldn't resist putting like a real racing type drag race setup on it just to see what kind of numbers that will make now remember we're still on pump gas and we have 22 degrees of timing in it so we're going to have to be playing with a little to see where we're at this will be interesting that's a good carburetor great oil pressure all the vitals are good man man okay so the requirement was six hundred ponies right with no timing in it and we shut the pull down at six thousand six thousand five hundred ninety four horse at six thousand torque languishing around five hundred twenty four pound-feet at fifty seven hundred we're not even into any sort of tuning yet we're gonna adjust some timing on it and make some real power poles so the next thing we're gonna do is dig into the MSD and crank some timing to it so Wow MSD kind of made this any easier basically all you're doing is setting your waypoints these little dots for the timing value you want which there's 24 degrees in our case now the reason you can't just have one line go across without any dots as it actually needs to see certain points to the RPM range and just in case you're wondering we have twelve degrees of initial during starting and then it's basically a locked out distributor all the way across at twenty four okay for the real power pole we're gonna knock the acceleration rate down to three hundred rpm per second which will load the engine a little bit harder and we're also going to increase the RPMs from four thousand to seven thousand and we did sneak two degrees of timing it so it sounds like a lot of changes but we know where everything was before that these are going to be real power poles we're gonna start our data poles from here so [Music] oh yeah I saw some good needles there so we have 633 horse at 6400 rpm but the torque look at the torque 530 550 850 900 but look how flat it is all the way just this looks like our old six banger torque it comes off and just levels off that is a sign of a really really nice cylinder head right there like a really nice on there we get still flowing big air to make torque all the way up there well right now 35 is our number on torque so let's put another degree and a half or two in it and see what happens we're at 50 850 900 yeah that is a winter blend 93 octane fuel pump gas and everything looks great the ground strap looks great the actual center electrode looks great the porcelain is beautiful good tune-up for a carburetor I know it's not in fuel injection but too bad [Applause] [Music] all right last timing change was up to 28 degrees of timing now you keep timing things until they level off on pork the old adage for tuning is you time for torque new jet for horsepower I think it'll well it's gonna do what it was [Music] I did it did it right there and some please I just want to keep going that's why I keep going five made a fifty-five about 55 it's still making a 44 it's seven thousand Oh wasn't art do 61 did it love two degrees and absolutely I hate when this happens because we could literally spend all day here whaling on this thing we don't have to that our goal is six thing you know I know but from oh there's always more you know I'm saying there's always more all right now they're gonna be a little ticked off that it has a carbureted intake on it and lick my face do I care okay all right so nice job over over and out for more information about the parts and equipment used in today's
