4.3 L V6 engine in your 1990 Cheyenne was there a 305 V8 for that year and if so would you have to change the motor mounts or do any other mods if you install the V8 instead?

You go with a 350 instead.You need the engine with it's computer chip (you can place it into the v6 computer), knock sensor, injectors and TB unit, but since you are getting a complete 350 (and bypassing the 305), you'll have everything you need.Move the v6 mounts up a few inches to the v8 mount holes and bolt back in.Drop engine in place.Done.

Yes your wires will hook up and no you wont have to change the chip either. the wires will hook up but if it is a tbi you do need to change the chip or it will run lean because the timing of the fuel dilivery for the 305 is longer than the 350 and you will run lean so the chip needs to be changed to change the timing of the pulse.

Can a TPI set up and computer from a 305 TPI be used with a 350 block and heads?

Yes it does work. However you will also need to use the 22 lb injectors for the 350. To get the full benefits from the upgrade you should get a 350 chip burned. The computers are the same but the chips are different. This is all considering if the swap is for a lb9 (305) to a l98 (350).
