I'm sure thier is tech about this somewhere on here , but this is a last minute buy and I don't want to pass it up if I can use the motor , without the l&l stuff
Thanks

 

Will the 460 fit in your truck, yeah, but its not a bolt in type thing, 2w and 4w engine perches are different, and depending on what engine you have in yours now, but yeah, it can be put in there.

 

Sry its a 351 modified in my truck , I'm going to buy the 77 3/4 whole truck , I was hoping most of it I could get in parts of 77

 

You will need the conversion mounts to go from your 351m stands to the 460 mounts. They are not very expensive, or you can make your own. The motor will bolt up to your factory 351m transmission if you have the auto C6. If its a manual it probably won't. Very hard to swap an auto 460 into a manual truck and have everything work correctly.

Everything else will work and the wiring harness should even match up.

The oil pan will also need swapped for the 4wd one, napa or jbg are your best bet as I believe you'll have to change the dipstick and pickup as well. Otherwise it will hit your diff the first big bump you hit.

 

Ok thank you very much , thier both auto , I will go buy it tonight or 1st thing in the morning if the ole lady has used all my home stash

 

As far as the oil pan swap he meant to say change it from a front sump to a rear one and yes on the dvrs side dip stick versus the front timing cover one.

Do not know if you HAVE to change the front cover or not, there is a real good tech right up here...seals can be an issue.

And here are some motor mounts that are HD.

Also a great time to look at fenderwell exit headers IMO. I believe if its a 351M with a NP435 or T18 now is will bolt up to the BB pattern.

Keep us posted with pics please.

 

The stock 460 truck exhaust manifolds will do just fine. The 460 will need a 4wd oil pan, front or rear sump will both work. My brother got his at a discount from a local napa, the whole kit with oil pan, gasket, dipstick, and pick up, for like $190, I think. That was for the 7 quart. JBG has everything in a package for the 10 quart for $375: 429,460 OIL Pan Kit 10 Quart

Nice but expensive. You should be ok with the stock front timing cover and all that, the accessories should be fine as well.

I did not use L&L motor mounts but would based on their reputation. My mounts are just welded steel copies of the L&L's. There are several companies that make mounts, I'd just go with whatever is easiest or cheapest. Some people say the L&L's have separated where they are vulcanized rubber. My truck does not have much vibration or anything with the solid mounts, and if you are handy with a welder they wouldn't be hard to make. I wish I'd taken pic of mine before I put them on.

I dunno what else to say. My 351 was a boat anchor, though it wasn't healthy. The 460 is a different world.

 

Thanks guys , I will start a build thread with some pics
Truck is going on 2.5 ton rockwells 4 linked 30" of lift on 62" tractor tires
I'm going to pull the 351m anchor out and wait until I get it lifted to put the 460 in so thier isnt as much weight when its 6 ft in the air on jack stands

 

If that is your plan I would reverse mid mount the engine & trans.

 

Trans is staying mounted , I have a crane and a platform to put the motor in when I'm ready

 

stock 2.5 tons won't last long behind 62" r1s, especially if you are gonna lock them. Thats pushing the limits of even the factory rockwell parts. But I suppose nothing wrong with wheeling them, and if they break, then they break. This company has a really good reputation for building the best 2.5 ton parts: :: Ouverson :: Hardcore Off-Road Parts 2.5 Rockwell Axles & Home of the Violator Series Axle Shafts

Anyway even with the top loader axles, with 30" of lift there is no way you are gonna be able to do driveshafts with the factory transfer case, even double CV shafts, which are $$$$, are gonna be past their optimal mounting arrangement. You will probably have to either clock the factory box at a ridiculous angle that may not oil properly, or invest in a drop box. SCS is the cadillac of the drop boxes, and for a lot of applications, maybe the only game in town.

And once you do all that, a stock 460 is gonna be the minimum you'll need to spin 62's. Most of the guys running tires like that are running built motors.

Maybe you've already thought of all that. Just pointing it out. Its easy to have big dreams and there's nothing wrong with that, but you have to have a plan you can carry out one step at a time to get there.

 

Yes I know about about the aftermarket axles , if it comes to that point I will buy them , I didn't want 5 tons , and the 62 are 18.4r30 R2's , I got em for 400dollars with the wheels and thier almost brand new , for a transfer case I'm going to run the stock 205 doubled with a 2.5 ton 12" drop sprag case which will make it 4-1 , I don't want to race it just play around and be able to creep through the stuff 44's are tached out trying to get through
I just wanted something bigger so I gonna build it

 

You will likely have to change the engine mounts on the front crossmember. The transmission mount sometimes needs to be switched depending on the width of the transmission cross member. You probably have a c6 on the 351m and on the 460 truck. Both trannies have the same bell housing bolt pattern.

I found it easier to just pull the motor and transmission at the same time. But then again I used a 2x4 to pry my 460 motor out of the engine bay on my '73 when it got a bit hung up. removal is easier.

 

when I did mine (and holy crap this thread came bftd) I just pulled the 460 off the 2wd truck by itself (no trans) and pulled my 351 and dropped the 460 in. Just like magic. I am now swapping a 4wd oil pan on after denting my 2wd pan on the front diff, but that won't be an issue with 30" of lift anyway.

 

Lol well it isnt that old , but yes it has been a few months
I went ahead and bought the truck I wanted the motor from ,
But before I got around to it I found another 78 that already had a 460 in it and looked a lot better than the truck I was working with ,
I have pictures in the project section under 78 f150 rocks and v-treads
