DonnyD,
I have a similar build in my 1970 GTO. I'm not a racer,but I think it is a low 12 or high 11 second car. It is a 461 with the same heads you have, but my engine builder does his own porting and won't tell me the numbers it flows. It has the same EFI as you. I would listen to B-Man on the transmission. I like to stir the gears and have a Tremec T-56 Magnum in it. Rear gears are 3.73.
The cam in it is one level lower than what is in your engine. Comp Cam XR-288HR @ 110LSA and 1.65 rockers. If I'm not mistaken the cam you have is the one that Butler puts into its 600HP engines.
The car has suspension and brake upgrades I won't go into here, but to give you a look and sound you might have look at this video.

By the way, I live in Connecticut and plan on moving to Sarasota as soon as the house sells. Maybe I'll see you down there.
