I would like to swap the V6 in my 1991 chevy 4wd pickup with a 350 V8.The truck currently has a 4 speed with O/D. I would like to know if there is an after market swap kit or at least a complete parts list required to make a reliable and sucessful swap. I would also like to know if I need a new computer configured for the 350V8 and if the original wiring harness has all the required plugs for additional sensors. I would like to retain the current emmission controls thru TPI or throttle body so I don't have any hassles for an inspection sticker. Do I need additional sensors? If so any professional literature such as a factory manual or "complete parts list" would be greatly appreciated.

is your truck an s-10 or jimmy? is it a 4.3? there are kits avalible to convert your s-10 to a v-8. i don't remember the web site but i'm sure it's fairly easy to find after all someone did it to my jimmy.if it's a 4.3 liter all that is is a 350 with the front 2 cylinders cut of essentially.it is possible that you might have to change your chip.if you us a tpi you will have to find the correct wiring harness.you might have better luck finding a wrecked 91 comaro or firebird with a tpi it will have everything you will need for the tpi including the chip or pcm.

i almost forgot' if it's a 4.3 liter the tranny will bolt right up.

I might be wrong but i think that when the state test vehicle emissions the go by a set standard for every vehicle. If this is true, by the time you get your V8 to produce as low emissions as the V6 it will be less HP.
