I am not doubting that more cam, compression and carb would really make things work. From what I gather these things love CFM. I know with my first 440 every size I went up in CFM netted me solid seat of the pants performance improvements.

However, it is a budget thing for the time being and the carb is basically brand new sitting in a box and this is the project so I need to use it right now.

It is the 80508SA Holley which I understand is a close relative of the 3310 with an electric choke. Please correct me if I am wrong.
