THE OTHER BIG BLOCK-MILD & WILD 460 FORD

welcome to another episode of the other guys here's an experiment get a group of guys together mention the word big-block 8 out of 10 guys are immediately going to think big-block Chevy maybe 9 out of 10 but today we're gonna take a look at one of the other big blocks how about some performance mods on a big-block Ford in this video we started out where we always start at the wrecking yard and we were lucky enough to find an early high compression 460 although you could do these equally well with one of the late-model fuel injected for 60s but we found this early model with high compression and we subjected it to the normal modifications so if you're a mild guy we got something for you if you're a wild guy we also got something for you on the mild side we subjected our 460 to the usual performance modifications we put a mild camshaft in it light be ported saw kids and a four-barrel aluminum intake manifold and that combination works real well for a truck or RV even a street strip fox mustang it would be awesome if you're a wild guy and you'll want to go run tens we've got a 460 build for that too we went bigger on the camshaft bigger in the porting and bigger on the intake a single plane with a Dominator so what do they both make let's find out before we get to the diet results come on guys make sure like share subscribe bring the bill push those buttons down there help me out tell us some friends get them over here we're having fun over here and by the way unfortunately this test was run a while ago and I don't have video of the motors running up on the dyno but what I'm gonna do is I'm gonna make engine noises in background Wow those are my junkyard special effects let's check it out to get things started we went down to the wrecking yard and picked up a 460 now you're probably the most of them you're gonna find are gonna be the late-model fuel-injected versions and the full-size trucks and stuff but we were lucky enough to find a real early one for this test we actually found it in a Lincoln and this was a 1968 version so it was kind of cool the benefit to that is that we had higher compression so these early ones had higher compression they had smaller chamber heads and more compression more power so this particular one was in the neighborhood of ten to one and as we would find out later when we took it apart to do some major modification suit and we'll get to that stuff to this one turned out to already have some work done on it it had 30 over Pistons now they were 30 over factory replacement Pistons so somebody had gone through and rebuilt this at one time in its life which is not unusual for something this a 1968 460 and this is another one of the other guys combinations I know that a 460 is not quite in the same league as a 400m in terms of you know it's much more popular than that combination but in terms of big blocks compared to a big block Chevy a Ford is definitely an other guy I mean the popularity the big black Chevy is much more than smaller than a big-block forward and and I'm not putting it down I'm just telling you that if you look at sales and stuff that's a reality and I don't know why that's true but I don't know why it's you know why that happens because a big black Ford as will show you here is a good combination they are available in the wrecking yard and you can make lots of power from especially with all the heads that are available for me Kazi has stuff air flow research has so obviously Edelbrock and there's you know there's a lot of good head joyce's out there for but anyway our 460 was a 1968 version and what we did was put it up on the dyno and run it in stock trim with long tube headers we also had to put a Holley carburetor where we put a Holley 750 on it because the factory carburetor was missing as was the factory distributor but lucky I was able to get one from my buddy Mark Sanchez shout out to mark there and we got this motor up on the dyno and running with long tube headers and that Holley carburetor our 1968 high compression 460 produced 349 horsepower and 492 foot-pounds of torque so as you can see even though this thing is a short stroke and a big more big bore compared to like a big-block Chevy the combination still was designed to make lots and lots of torque and it does that basically just cause of displacement because it's 460 inches so they have put the camshaft in it and obviously our early motor even though it is an early one and it's a hiker pressure one does not have Cobra Jet or Super Cobra jet heads on doesn't have the big valves or anything in it but it did have a high compression so this was a good baseline starting point for us now let's take a look and see what happens after we made some modifications after establishing our baseline with our 460 with all the stock stuff the only thing that had different was the 750 Holley carburetor and the long tube headers they had the factory iron intake and factory heads factored camshaft factory rockers all that stuff so we started to do some modifications to it the first thing we did was install a we replaced the iron factory four-barrel intake because that 460 came from the factory with a four-barrel we replaced that with a wyan intake manifold so let's take a look at that and that's interesting the Hawaiin picked up power past 3500 rpm which we expected to power went up from 349 up to a peak of 364 yea 364 but take a look and see what happened below 3500 so if you've got a truck and you're doing towing with it or a Motorhome or whatever you might have for your 460 in take a look at the loss down here I mean it's pretty substantial you're talking about 487 versus 452 so that's like 35 foot-pounds so the wyan for barrel intake did improve power out there and it's and it feels like it's about 500 pounds lighter than the factory iron intake manifold but the iron intake manifold was designed to really enhance torque production down low and that's exactly what it did so that's something to think about if you're thinking about upgrading the intake manifold you got to pick your rpm range so the next modification we made and we're gonna do a bunch of mild stuff on this thing first and then we're gonna go crazy with it and get a little bit Wilder so the next thing we did was a set of rockers and as you can see there was almost no gain there and what we did was replace the factory rockers with a set of aluminum roller rockers when we thought no that's that's definitely gonna help but as you see here there just wasn't much gain now it look like it's was starting to trend like it wanted to pick up power at higher rpm past 5500 but through most of the curve there was just no difference in power and normally we would expect there would be because we know that kamme change will definitely make power on these things but for these rockers did not work but the next thing we knew definitely would work so let's take a look and see what happened when we installed our camshaft so we put an extreme energy 262 camshaft in it and as you can see it picked up a ton of power picked up power through most of the curve we even managed to reach right at four hundred ninety nine point five foot-pounds of over five hundred foot-pounds which is a good number but everybody I'm sure is looking at this big drop out here and what that is is valve spring so we did upgrade the valve springs on our big-block heads we put the specified springs for our 460 or two sixty two camshaft and the problem is that they're still not enough spring so installing the combination and and in truth it is a combination of two things it's a combination of the more aggressive camshaft and it's a cut and the roller rockers that we put on because whenever you install roller rockers they're very heavy relative to factory rockers so the combination of the cam and rockers produced a valve flow problem and the reason that I didn't do a valve spring upgrade and cure that is because the next modification I was going to make was they said of mildly ported heads that already had a valve spring upgrade so basically I just got too lazy didn't want to do this because we knew we were swapping the heads anyways and we're gonna show you what happens when we put these mildly ported heads on and we also cured this valve spring issue but you'll get to see what happens okay here's the difference between our baseline motor and in stock trim with the headers and the integument headers in the carburetor and then after we installed the camshaft and the rockers on and the Y in intake you see we've got valve float but I didn't want to change the springs because it was a lot of work just to change the springs cuz I was just gonna have to change the heads anyways so here's how we cured this we put a set of mildly ported heads on when I say mildly I mean it's something that you guys would do I would do even having never ported a set of ford big-block heads it's something that we would do you just do it intuitively I mean you'd go in and just get rid of all the flash and Boal maybe make the ports look better by making new shinier and stuff this is this was a very minor amount of porting I think that the thing that helped out the most as we'll see we were allowed to rev this thing because we put the right spring package in it and these ported heads and the guys from L&R machine Derek my buddy down there actually did these heads and they did a good job on them so we'll take a look and see what happened when we install these and you can see that's a that's a really nice power curve I like that power curve it goes all the way we ran it all the way out to almost 600 again this is still a mild flat tappet camshaft I'll go ahead and put the specs up here because I didn't mention those before on our extreme energy 262 cam but it's a pretty mild cam at like - 12 to 18 I think is the duration on it so this is a really good like streetable 460 package and sure it has high compression but if you were putting together a 460 anyway even if you started with one that was an originally an EFI mode or something you're running at carbureted you would probably put a piston in it so if you put a piston in it just put a piston that's gonna raise the compression if you do minor porting and honestly I don't even think you have to do the mind reporting it's gonna help a little bit here but what I would do and we didn't do this on this one is if you wanted to get the extra power not pour the head I think you could switch from the yn four-barrel intake to like an RPM air gap I think an RPM air gap would make more power than the yn does on this combination so if you have you have a good head and a cam like that a mild can because that's that's something you could just drive around with it you can see it didn't really lose any power the power that we lost down low was from the intake manifold and you still have that with the rpm air gap so that's a combination I put together this is a good combination with the white intake and that four-barrel carburetor and the ported head on our stock short block that worked out well maybe try the rpm air gap if you want to try that if you don't want to do the port head so you maybe trade those two and get the same thing now let's take a look at see what happens when we basically throw the kitchen sink at it okay we're gonna we're gonna basically upgrade everything we're gonna make a lot more power and to that we basically need a lot more of everything so I'll show you what happens when we do that when we left our combination we had run our you know mild 460 forward from the wrecking yard and we had done a camshaft upgrade and an intake up create and the cylinder head upgrade all basically on the mild side the camshaft was pretty small the intake was a yn dual plane we had already had the 750 Holley carburetor and then we installed those very mildly ported factory heads and picked the power up to 437 horsepower and torque was up over five hundred foot-pounds which is nice 507 foot-pounds so that's a good jump from the 350 horsepower 492 foot-pounds of torque that we had run with a stockman butt and that's a good way to go on our mild combination but we wanted to go even farther so we wanted to show somebody what could be done to really get a lot of power out of the 460 and what we did was we didn't go the whole stroker route but what we did was took the took everything apart took our short block down to the guys that Ellen R and I had Derrick board 60 over and then we put a set of flattop Pistons in it then cleaned up nice and they had the guys have a 60 over flattop piston without police in it that allowed us to run even more camshaft because that was really the key the short block prep was kind of minor compared to what was going on but we put that flattop piston in to bring the compression up we also got in contact with our buddies at mpg who are the Ford Cleveland and 460 specialists I met these guys during the engine masters competition and there's some there's some serious hombres I mean when they told me that they were doing a 410 inch eight-point-two deck forward I thought that's the most foolish thing in the world and then I saw it I saw what it did now I'm like that's the most awesome thing in the world so they're great guys and they know what they're doing I told them what I want to do I said look I like this 460 to make 600 horsepower they said okay no problem and you want to do it with the iron head I said yep they said okay I'll give you our 460 cylinder head porting and our 460 600 horsepower head and cam package basically and all you have to do is take that head and camshaft put it on that 460 and especially if you've got a flattop piston if you put a good single plane intake manifold on it will make 600 and if these guys tell you that it will make 600 it will actually make 600 so what we did was we took them at their word I sent them a set of iron heads they ported him up they sent me a flat tappet camshaft which was kind of Hydra or a yeah a solid flat tappet camshaft which was awesome and we put that on and we installed it with a single plane intake manifold that we had on one of these big crate motors from Ford Racing so it was a an L Brock single plane intake and here's what happened we went back package and the cool thing also is that the Edelbrock intake manifold that super victors Victor jr. whatever was off to take a look because it was made for Ford Racing that was set up to accept a Dominator carburetor and although it really didn't need it at this power level having a Dominator on your Ford 460 is like super awesome so equipped with that cylinder head and camshaft and intake manifold the power output of the 460 jumped to as they said it would over 600 horsepower it produced 609 horsepower and peak torque was up by quite a bit as well 557 foot-pounds of torque and I'll make sure that I put the cam specs in so you guys can take a look at how much camshaft it was it was a healthy cam and as you can see down down here below 3,500 we're definitely going to trade power compared to the very mild stuff that we had in the very mild combination so if you're choosing between these two there is a choice between the two you have to look and say hey look I want that and I'm gonna be doing that with it with gear and whatever that you need or I'm gonna do the other one and it's a mild combination and I don't need this kind of power I don't need the extra 150 plus horsepower I'm more interested in having the torque down low so that's why I'm showing you these do two combinations and it goes to show you the even the other big block this forward big block can be made to produce either one of those things and really anything in between and as we'll see later on I'll do another I'll do another video later on down the line and show you how we go up another improve the power output 50% from here and because this is a good combination but there are ways to get even more NA power out of it so let's get to work and glue what did you guys think about our other big block buildup I mean I like the 460 personally I think it's a good combination especially with all the aftermarket heads that are now available for it I mean airflow research Kazi Edelbrock trick flow I mean all the guys have cylinder heads for them and they all work really well so you can make a serious 460 there's still a lot of them in the wrecking yard especially the late-model EFI ones and if you're gonna change the heads and the cam and put Pistons in it anyways you can make the compression whatever you want but on our combination I purposely wanted to stay with the stock heads especially on the mild build because the guy already has that V goes to get it from the wrecking yard and you can do a little bit of work yourself in the porting put a mild cam in it put an aluminum intake although how did you like the difference between the aluminum intake and the factory intake the factory does a pretty good job make it those would things work at low rpm but how about that wild combination big single plane intake Dominator big camshaft fully ported heads those guys at mpg they're the real deal they know how to make horsepower but if you want even more power let me know in the comments I've got some big stroker versions over 500 inches all the way up to the 557 stuff I've got some Kazi head itself I've got some trick flow a 460 headed stuff we've got some big power let me know if you want it thanks for watching
