I’m doing a carb swap on my 91 tbi 350. I’m getting the parts together and have a question about carb size. I would like to put a 650 on it, but have access to a 3310 750 vacuum secondary Holley and also a 450 cam Holley. The truck is a daily and is stock for the moment. It will later get a mild cam. But that’s probably about it. Is the 450 going to be too small. And in the thought process will the 750 be too big.
