I need some advice.

I have a 1986 G20 with four barrel carb with blown motor. Rod went through the block & cracked corner off.

I have a 89 Chevy truck with 4.3 TBI. Neither motor has counterbalance shaft.

Want to use the 89 4.3 in the 86 G20 and have G20 remain as carb.

1. Can I switch 86 manifold with carb directly onto the 89 4.3?

2. Or can I switch heads, manifold & carb onto the 89 4.3?

3. Can the TBI cam be used with carb or can the cams swap between the two motors.

4. Has anyone drilled the TBI 4.3 for the mechanical fuel pump rod and the drain back hole?

5. Not interested in a hot rod build just want to fix so I can tow the boat & go fish"n.

First Post!

Thanks in Advance!!
