: 460 in a YJ swap

ok, the 4.0L has served me well, but is way too gutless for my tastes, powers out too easy in the mud and snow and long sandhills. I also happen to have a 78 f250 that is in need of some rockwells and a bigger nastier engine. so, put the axles (hp44 and 60 rear), 435 trans,205 t-case under the jeep, from measuring so far, looks like the engine is actually gonna go easy, physical dimensions wise (smaller than a mod motor). with the full length ford truck headers, they exit down the pass side anyways. its a pretty hot engine (450hp or so) with alot of grunt still so should be perfect. has anybody tried this?? engine mounts?? anything close? block side is no big deal, but it looks like im in for fabbing new frame towers to get the motor down low, i want it under the stock hood. hoping there is something out there thats close. motor mounts are the only thing thats making me really nervous about starting this right now. biggest reason i have to put a 460 in it, is because its not another chebby or small ford, and i have yet to see a 385 series powered jeep. any help or guidance is greatly appreciated, JR

I was considering a 460 for a YJ project and found information from Ford Mustang guys who fit them down in place of 5.0 liters. Mac has a header that tucks in nicely and I don't remember the motor mount kit ? You may be able to get something from that Mustang 460 kit to help your YJ build ?? Hope that helps, good luck.

with the power that can be pulled out of big inch small blocks, either ford, chevy or dodge, I think putting a big block in a jeep is like shoving 10 pounds of shit in a 5 pound bag. THESE ARE LIGHT VEHICLES AND DON'T NEED THAT MUCH TQ... unless you plan on running around 40" of tires and I still think its a bad idea.

edit - gears are the way to go with the larger tires

Welcome to Pirate4x4 you need more than gears to have fun :flipoff2:
I agree a BB is a beast but to each his own, i`d go Ramjet350 or a 5.0 :D

SEMA - wouldn't exist if it wasn't the Largest Group of misfits using "BAD IDEA's" to build some of the most Wicked Vehicles ever to grace our beloved trails !!

I'll agree you don't need it but I wouldn't say it's a bad idea, just different and I do like different.

i agree on "you need more than gears", but with a big inch small block I think there is tons of power there in a much smaller package that makes lots more sense. i agree completely with a ramjet 350 or even 383. If you wanted to be different I would look at a 454 small block chevy. Good axles, lockers and gears are the way I would go, but thats my opinion and we all know the phrase about opinions and assholes.

as far as SEMA, half the shit there is dumb and the other half is retarded (alright give me 49% and 49% cuz 2% is actually worth a shit). Yea its all crazy but that does not make it good. I saw a guy with a viper v10 motor in a wranger once, and he could easily smoke the 38s it was on, but smoking tires does not help on a trail. I have seen 35s smoke with a 350. Having been to SEMA a few times, I have never seen one of those vehicles on a trail, they are to pretty and to flashy for the most part.

for my 88 yj build i'm getting a 351 built to drop in. Mating it to a c6 trans and either a np205 or dana20 tcase. The engine will be making 500+ hp...engine is not as big or heavy as the 460, and will be making more power. I've also found engine mounts they sell to weld on the YJ frames. Novak conversions sell em.

I don't think any shoving is required! My BB chevy is no where near cramped! If you got it run it! Thats why mine has a BB, I wasn't gonna buy another motor when I had it sitting there.

500 inches of big pimpin caddy......:grinpimp: . Lightest bigblock and make killer low speed and midrange torque. Plus they are different to boot!

see, the reason for the 460 is, its only 150 lbs heavier than a windsor smallblock, i can get the same power out of a big block for half the money with alot stronger bottom end. for a given power, you have to turn a smaller motor tighter. the motor im puting in is a legit 450hp, not somebody's bs inflated numbers, that takes alot of money to do with a smalblock and have it hold together, still well in the realm of stock rods and crank with a big block. weight difference is between a fat chick and a skinny one. no debates here, its getting the BBF (my great big amazon chick). (they weigh right on 650 lbs with alum intake, small chebby is 500lbs at best, 351W ford is about the same, big chebby is around 20 lbs lighter than a 460 from what i hear (all alum intakes, iron heads). BTW, will be running the tires that are on the truck 325/85/16 XML, 14ply (sit bigger than a 38.5 swamper) so they are heavy and need some power to turn. they might have to go we'll see. i have a 2300lb car with a 521ci BBF with a-460 heads (right at 800hp), so this isnt even overkill around here:D. sounds like the mounts are gonna be the bitch. might just be easier to just fab it and be done with it, instead of tryin to make something else work, but i'll check those novak mounts first. hope to get started in the next month, as soon as i find a shop for the long term. dont think it should be too tough, but we'll see, any more input is appreciated.

Ok....you want to go for 'bitchin' value......how about a Viper engine or Dodge Hemi?

vipers are v10 = GAY and hemis are too damn heavy, and expensive. 830ishlbs for the 426 style, 800 for the old school chrysler, i thought about doing a 392 a while ago but decided against it, cummins 5.9 was also considered but again, too damn heavy like 1100 lbs. take the motor out of my cobra and put it in there, that could be fun, god help the axles. the other reason for the BBF, is its not too hard to build a 545/557 out of them if i decide its still lacking, and they are pretty cheap to build if you know where to get parts. main thing is the potential for more power, cheap and reliably, i dont want something that is pushed to the ragged edge to do what i want.

I bought a 460 to put in a Mustang once. When I set it in the bed of my Nissan truck, I thought the tires were going to pop.

I said "screw this..."

thanks for lookin, u know, i might be able to use 351W towers, the block side i already have a set built and some more plates cut for another set if need be, i went through this already putting the biatch in my truck. if i can cut down the towers, it might be a good place to start.

got a 392 down to 570lbs and my 354 that i put into a cj7 weighed in at a healthy 540lbs cast heads aluminium timing cover, water pump and aluminium intake. dont forget the amc 401, aluminium heads aluminium intake and fi 434 hp and 491 ft/lbs dynod at the flywheel. seriously the ford 460 is a good choice though i would opt for a nv4500 tied to a built d300. the 401, 454, 440, 460, 500 caddy even a 396 amongst many other bb's are great at providing a wider more usable torque curve than any of the sb's that are out there, im still not too sold on strokers. just my personal opinion. keep it simple. Loved a chrystler 383 in a cj it wasnt too heavy and it had great low end grunt and stil could wing 6000-6500 rpm. currently happy with my 401 in my cj8 then again im a freak and dont mind having lots of hp on tap and having the 4.88+ gearing too

I strongly encourage using this motor. Run what you got and there is no such thing as overkill. :skull:


HOWEVER, placing the motor between the horns seems like the easy part. I would imagine having a hell of a time running the steering and keeping it cool would be the top concerns. Just hoping to keep the cogs turning and to help you think about placement of the motor when fabbing some mounts. ( give yourself a little more room on the driver side for the steering ) :idea:

That'd be my biggest concern.


(Oh, and to those that want a big inch small block......:flipoff2: He already has the 460 with the performance he likes. Why change a good thing and spend more $$$$?)
