Who ported your heads? I assume since its a street car your running on pump gas? Your cam in similar to my old 331 cam. Well in lift. It was an off the shelf cam. Its nice to get one of those when ya ask for a custom one.
My heads would probably have better numbers on a different bench, but the bench they were flowed on is known to be pretty stingy on its numbers. The big bores definately help out TW heads.
There is a posibility when I get my front struts fixed I am gonna step up to 4.88 gears. What kind of power did you put down at the rear wheels? Last time mine was on the dyno. It was putting down like 472rwhp, but at the time I didnt know my timing pointer was off, so who knows what its making now.
