4.3L TBI to Carb swap HELP!!
 

Hi,
I've done a bit of messaging for my '70 C10....

Recently bought a rat rod with a 1985 (blown up) Chevy 4.3L V6. I'd like to get another similar engine and swap it out. Turns out only 1985,86 came with carbs. I can get an '87 but it's TBI. Will my current intake manifold and 4 barrel Holley bolt on correctly??? It's my understanding that in 1987 the engine came with a roller cam that might have clearance (in the valley) issues. Any suggestions welcome!

I have: 1985 4.3L Chevy V6 - see pics.

I want: similar engine and use my existing parts, including intake/carburetor.

Thanks!!
