Ford 302/351 swap info
#21
IMO you need to set some goals if you are serious about this
-what is it being used for? Mud, rock trails?
-how much power do you want?
-what is a realistic budget?
These make it much easier. IMO I would simply just get a used stock mustang 302 roller (HO) FI engine out of a fox body complete for like $500ish and go from there. They came with forged internals and can be pushed to 600rwhp if neccessary, parts are overflowing out of every corner of the market, technology is booming for it etc. It is a relatively light and compact engine as well. Get one, slap a 8psi supercharger kit on and you can have a reliably 400hp engine no problem for relatively cheap, get good fuel economy, be docile as well.
if you got a 351, you could stroke it to 408+, but again, parts are much more money, do you really need 700hp?

Im still swaying back and forth between the 302 and 351.... its goina be one of those. 300RWHP would be more than enough for me. it all just kinda depends what i come across first cheap, 302 or 351.
Correction on the trannies... 89 F250 2WD had a E4OD... but i dont know if you could get it in a 4wd... I havent figured out what axles im goina wind up usin yet... but im leaning towards non-toyota. still thinkin bout narrowing a wide front to use for rear steer... but the more i look at different front axles, the more i think its not possible.

If you are thinking Fuel injection I would stick with the 302 (5.0) becaue the EFI system is easy and parts are really available. Could easily push 350hp with out a turbo or sc'er. Keeps it really reliable. Just go with a 1990 or newer so you have a Mass Air engine instead of a Speed Density puter system. I hope you do this either way. Your Runner will be a monster.

302= W 18 3/4" & 20 3/4" H
351W= W 21" & 23 3/4" H
Length depends on what front timing cover you use. On the average it is 27 1/2"
Height is measured from bottom of oil pan to top of valve covers.
I would stick with the 302 since more parts are out there for them. Some 351 parts with swap with 302 like, timing cover, cylinder heads(302 is 7/16" bolt holes, 351 are 1/2" but the 302's can be drilled or the 351's can be used on a 302 with a bushing adapter), upper intake if it is FI, cam, rockers, exhaust manifolds(depends on application) and some brackets for accessories.
What you can use is the HO motors since they have forged pistons, roller cam and dual roller timing chains. These are in Mustangs, Lincoln Mark 7 LSC's from 85-92. You probably want speed density system meaning non Mass air unless you are planning on putting cam or any other mods in the motor. For what you are doing, the HO speed density motor will work perfect for you. You will have plenty of torque, great idle and cool sounding exhaust. If you are interested in any parts, let me know. I have just about everything you need.
One thing more I forgot to mention. You can build one hell of a stroker motor for the 302/351's at a very reasonable price. How does 347 cubic inches sound just by using a 302 block? They would give you TONS of torque if for some odd reason you werent happy with just the SD HO unit.

LOL the ls1 is staying where its at plus ive been told they wont fit, too big
what kind of numbers did the HO 302's put out HP wise... I'd like to be around the 250 to 350 RWP range when its all said and done. If figure around there i'll have the power to do what i want, but not soo much power i'll need huge beefy axles.
Thanks so far for all the help!!!!

One other thing. You can use a SBC but the Ford fits better since it is narrower and the distributor is in the front so you dont have to worry about firewall issues.

i was gonna post the cardomain site about the guy who booty fabbed a 390 into his toyota. then again, at least he had the cajones to give it a shot. i never would've imagined a big block would ever fit in a toy bay...
i thought about doing the 302 swap, the only thing that held me back is that i would never run an auto tranny, so you're limited with viable options: go with a huge NP435 4 speed, use an adapter and run a G or W tranny(bad idea imho, too weak) or spend a bunch of money on adapters and put in an NV3550.
the ford is a little bit longer than the chevy, but lacks the distributor clearance problem and the width is nice. then again, i've seen a 350 swap that looked like it fit great in a toyota, so i guess everything is possible. go for it!
