TBI Questions
 

How tolerant is the factory TBI to bigger cams, valves, and headers?

I was looking at an 87 with factory TBI on a 4.3 and was wondering about the feasiblity of swapping in an older 350 with 492 heads, headers, and a mild cam.

Anyone have any experience with swapping a small block for a 4.3?

my buddy has a newer model with tbi. it is about a 91 model and he put a 383 with a larger cam, he hasn't had any issues with it at all.
