changing engine sizes? lo

[TwoX]

ok so i have a 78 ford parked out back with a 390 bored 60 over, i was thinking when i get my new truck, taking the 390 out of the ford and trying to put it in the toyota, ive seen toyotas with 351s, and 302s so why wouldnt a 390 work? i think it would be a bad truck, seeing how once i get my new truck the toyota is gonna be used as a mud truck.

that would be pretty awesome but it seems like more trouble than it is worth. and if it is just going to be a mud truck why do you need a bigger engine. It would definately cure the slow problem but since you said it is just a mud truck I would leave it alone.

Any engine would work ...


















if you have a plan.












What's your plan to make it work?

Can't give an educated opinion w/o some details. :biggrin2:

i looked at a '86 toy p/u with a 350ci paired with a turbo350 tranny. i sound good but was done poorly. Engine was mounted straight to frame (tons of vibrations) and distributor cap was about 1/16 inch from firewall. headers squeezed up against the fender wells. AC condenser wasnt hooked up. i guess what im saying is think over every aspect of engine swap very carefully. i personally like my 22re, simple motor to work on, lots of parts.

it was something i was just thinking about, the guy who is working on my head gasket said he could do it but it would be about 5 grand to do the swap, because he would have to custom make alot of the stuff

That's actually a lot of BS, 'cause AA makes everything needed to do a 350/TH350 or 350/700R4 swap. No/little custom work involved.

but thats a 350, this is either a 390 or a 460

Correction to the above, any motor that will fit will work.

I've never seen that particular motor used but if you can fit it in between the frame rails, and between the firewall and radiator you can make it work. But as you're finding out there is a ton of fabricating required and unless you're very handy with a chop saw and a welder I would recommend using a motor with aftermarket support for your swap.

There is excellent support for the 3.4L Toyota V6 swap, and as well for the SBC 350/TH350 swap, and a little for the Ford 302 as well. No matter what option you choose you really need some sort of suspension lift and a body lift to make it easier but I've seen it done even to a stock height 2wd truck before so you're really only limited by your skill and wallet.

If I was going to do it it would be the SBC route. You can literally buy ever part needed for the conversion from Downey and Advanced Adapters.
