I am stuck between rebuilding my Holley 650 double pumper or buying a new carb. I'm considering a 750 but not sure. I actually prefer a vacuum secondary with an electric choke.
Right now, my engine is a 351C with 4v heads, 224/230 @ .050", Torker intake (soon to be an Air Gap), C6 with 3.73 gears (soon to be 3.25).
I've been told mechanical secondaries aren't idea for the street. I've also been told a 750 is perfect for a Cleveland. Any ideas?
This is the carb I was looking at. It doesn't have any jets. Does anyone have experience with this type of carb?
