well having done quite a bit of research on this topic myself - - I can
offer you the following info:
V6-V8 swapps are not that complicated (yeah right Tom)... You do need
pretty much everything from a V8 truck. You may as well shop around for
a good donor - engine and trans running or not - if you are building up
the V8 or going to get a short or long block - you really want to have
the complete wire harness from the V8 to put in the V6. I wouldnt
recommend trying to jurry-rig a V6 into a V8 harness. And why mess with
adding injectors to the fuel rails? you can pick up a V8 manifold and
its componants from a bone yard engine.
You need the engine computer (make sure its a computer forom a manual
tranny donor truck - you dont want the computer trying to shift for a
trans that doesnt exist) - the compete engine harness - I dont know if
there are fuel pressure differences - you need to check to see if the
pressure requirements are different - though I think this is an issue
for someone going from a premag engine to a magnum engine. (but check
anyway - you may end up having to swap fuel tanks/pumps)
The frame should be able to handle the extra weight without mods -
crossmembers should be fine too. I assume you are going to swap a 318
engine??
I dont know if the coil springs from a V6 are rated to handle V8
weight - check to see if 2wd V6 and V8 coil spring part numbers are
different - if they are the same - you hav no problem. If they are
differnt - odds are you might need V8 springs.
I'm tired - prolly forgot some stuff - if I remember anything else
I'll post
