Carb Performance Question

Post by Aubrey3 »

I have a 352 with the 2100 on it. From my understanding it is a 300 cfm carb with the 1.14 venturi size. I do not tow or race it. It's a daily driver around town and on the highway running 75 mph or so. I am in Denver with thin air.

My question is what kind of performance change would I expect if I switched out the carb to a 1.23 or 1.33 venturi size (351 cfm, 424 cfm)?
