My buddy has a 400 a 351 and a 302. His truck is going to be used for mostly mud bogging what would be the best motor to go with in terms of power/parts/rebuild costs... Have matching tranny's and t-cases for all the engines. Drivline will end up being put into a 1991 bronco XLT and be converted to carburated. The diffs will be changed to solid axles and re-geared (dont know which gearing to go with yet)... He just wants a indestructable high revving block.

sell all 3 and get a 460. pretty much bulletproof, up to 7000rpm with the right cam and valve springs

Ive had all three motors, in the same truck. It was an 80 Bronco with 3.55s, and 35 inch tires. The 302 was BY FAR the best motor. I could rev the piss out of that thing all day and I never had problems. The 400 and 351M were just garbage. Always overheating and didnt like revving. Maybe you're talking about a 351W, if so, I dont know! Ive never had one of those!
Just my 2 cents!
The 302 also had alot more power, and it was a stock motor, no mods!

My current truck has a 460 in it and I love it, lots of power and likes to rev!!

I got a 351 w exact same block as the 302 but lots of high end power good to about 5500-7000rpm's without a problem so personally i would go with the 302 just for the simple fact that it has more bottom end torque than the 351's!

dude I think you got it backwards 351 windsor has over 100ft lb more torque than a 302 and more hp than a 302 also .

460, or the 400. Yeah Im one of those guys who says the 400s can be built to run. Having seen proof I am a believer. Just think about it, its a 351c with a bigger block the size of a 460, just a litte shorter. Its got a 4" stroke which will provide tonnes of power. The 351c is forever known as a performance engine by ford enthusiasts. Well a 351m built the same as a 351c puts a few more ponies out than the C...and a 400 is 50 more cubes (actual cid is 352 and 402).

I still personall would go with a 460, for the above mentioned reasons, and you can get parts which are from the same vintage, to swap into the bronco. 80-82 were the only years in the 80-96 vintage that got a 400/351m. They started getting 460s in 83 f250 and 350s and stopped in 97 F350s, more parts available via salvage.
Well then again 460s and 400s use the same trannies, so you could even build the 400 and use 460 drivetrain.

Just remember tho, the 460 will cost less to make the same amount of power.

for a big block go 460 and the 351/400m suck for they dont like to rev and for small block either one 302 or 351w they dont mind reving either

this is a stroker 400, to 434cid http://www.tmeyerinc.com/434dyno.MOV more info found here: http://www.tmeyerinc.com/400stroker.html
"Dont rev" haha, when theyre stock sure....listen to this vid. The dyno doesnt start untill 2500rpm. Sure not as cheap as doin a big block, when youre building an M block 335 series Ford engine, you actually have to know what youre doing. Instead of all the 5.0L or SBC guys just buy a part from the huge aftermarket and slap it on their engine.

so i guess ill look into just getting the 460 then because i have the drive train for the 400 and your saying it will bold up ill need new drive shafts tho lol blew them both in the same day at postil

Yeah, auto trans or manual? I think there was something in the torque converter and flexplate size that needed to be noted....otherwise complications could arise. Dont quote me on that, but you could go to FTE and check their "engine swaps" or "335 series c/m/400" forum to get more details.

Dude 351W all the way, parts are just as cheap and plentiful as the 302 and the Windsor has way more balls. The only problem that i have found with the windsors is that the crank journals get shredded after 160K so you will have low oil pressure untill you grind the crank and get undersized bearings.

I just cant see a merc (cougar?) engine running at high revs in a bogger. Sure a block is a block... but they've definitelly gotta be cammed different that a truck engine.

I got my 460 out of a 75 Lincoln Mark 4. I have absolutely no probs with that motor. It happily revs all day, and makes the truck almost feel light!! My truck is a 72 Ford 3/4 ton sittin on 38's with 4.10s, not a light vehicle by any means!! Im also runnin BBQ juice on it.
