ok,
lookin for some input. the mach has a 351c, w/ headers, exhaust, mild or stock camshaft, edelbrock performer manifold, and a 750 cfm holley carb... is it too big? its a 4160 double pumper vacc sec. and im trying to jet it correctly. it bogs way down when you mash it to the floor, and stalls out all to frequently. oh yeah im runnin it right at sea level. think i should go with a 600 or a 650cfm carb? not converting to efi. or can i run a small enough jet and power valve combo to make it work right? looking for the cheapest fix thatll work correctly. lemme know what you guys think. oh yeah timings good, and the ignition systems top notch. thanx once again ppl!

A properly setup 750 vac secondary should work on your combo.
Maybe your carb needs cleaning and new gaskets?Hans ------------------
