Dissapointing performance

Poorly carbureted and even more poorly exhausted. Cam is also a little big, IMO. As asked, what gears and converter? So far, looks like a bunch of mismatched crap. Except the heads.
Not any carb will ad 100 hp in it. or exhaust. Cam too big?? These heads support over 500 hp in theory. Are you joking I think this combo is good matched.
