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.
It's a 4160 750 CFM carb that doesn't have a rear metering block, doesn't have 4 corner idle and has a choke, all of which I don't care for. And that's just a cursory glance at it.
I realize that budget is a big deal, but I'd use the PTC converter you have and get a different carb long before I used that carb and spent money on a converter.
