I'm about to do a swap in my 87 toyota pickup—it's a 22r with GotPropane. Looking to put a 4.3 TBI into it, but pulling the TBI and putting the propane kit on it (mostly to avoid all the wiring crap, lol).
I've been researching it for hours and hours on this site and others, and I think I've got a pretty good grasp on how it needs to be done.
Anyways, I found a donor chevy astro, and I just wanna double check with you guys to make sure that I've got everything else.

-AA adapter
-clutch
-flywheel
-aftermarket motor mounts

This is all I can think of that I'll actually NEED to have (with the exception of a different mixer from GotPropane).
Will I need a body lift at all?
How does the exhaust work out best?
I have a radiator from a v6 Toyota, but is it enough to cool the 4.3? I can always do a v8 radiator mounted in the back if I have to.
With the propane setup, I won't have to deal with the ECU, will I?
Is the intake manifold on the TBI the same as the carb'ed intake, or will I have to get one?

Thanks so much guys!

 

Might check on aa headers, I know astro manifolds won't fit cause thats what I got my engine out of, possibly s-10? I'm running v8 conversion Rad. from be cool with flex fan. If you plan on doing low speed driving on steep hills you should consider a electric fan w/shroud especially if your using an auto trans. That's my next project because trans. temp really heats up even with 10k cooler. I also had to use 2in. body lift to clear stock air filter housing. Good luck!

 

I have a 350 in an 83' yota and I turned a pair of block-huggers upsde down and ran stacks out of the hood and put tractor flaps on them. It looks beastly, but you cant clear anything taller than stock valve covers.
