302 EFI engine swap
I posted this in the Performance section also:
89 Bronco with a 5.0 threw a rod, and I'd like to upgrade if possible. The FMS P58 complete engine (1997 F150 5.8efi) looks like a good buy, but I need a complete list of everything I'll need to convert from a 302 to a 351.
Sounds like a computer, flywheel, brackets and maybe a wiring harness. Has anyone actually done this swap?
My second choice is the FMS G50 engine - essentially the early 90's Mustang mill, and it should bolt right in.
Thanks-GP

302 EFI engine swap
Nice sounding swap and it should just drop in. The flywheel and damper will change, but I'm not sure of everything you're getting with the FMS 5.8. Is this a crate engine? You don't even need to get new brackets. FMS has an adapter when swapping from a 5.0 to 5.8, then everything else should swap.

I've done this swap in my 1990 Bronco. If you are getting a crate 5.8 eng you will need the following:
5.8 Intake manifold (upper and lower)
Water pump
Oil Pan
Valve covers
(all your gaskets will come with the crate eng)
Timing chain cover
Fly wheel for 5.8
Harmonic Balancer
Eng Mounts
Distributor, Cap and Rotor, Plugs, wires
ECU for 5.8 (possibly the wiring harness too)
Exhaust manifolds/headers and "Y" pipes must be replaced or widened. the 5.8 is about 2.5 inches wider so the 302 exhaust will not work. (I found this out the hard way
I think that is about it! Oh, I almost forgot - you will need to replace all the sensors, oil pressure, water temp, ect...
The switch to a bigger eng will add up as you can tell from above $$
I did this about 3 months ago and have some before and after pics if your interested. Let me know if I can help you out - I have definately learned some things from this swap.

What tranny are you running. if its an AOD then you will need a flexplate from a late 80's crownvictoria with 351/aod combo. your accessory brackets & wiring harness from the 302 will fit onto the 351w mine did. I did my swap a year ago and was a good investment.
species has covered everything else though.
