Ok, learning everyday from the Pro’s on here, thanks in advance !
I have a 383/489 with flat tops. I was going to use a set of ported 516s I bought and swap to dish pistons but I just got some Stealths to use instead. So I’m keeping the flat tops. ....
4.5cc, 82cc, .051 gasket and comp roller with ...57* ivc, I end up with 11-1 with 8.33 dynamic.
Chambers may end up to be 84-85 and I’ll use a .040 gasket. Will be using pump 93, in a mini tubbed dart, 3500stall, 4.10s, 28in tire....... Tunnel ram, 2in headers, Street/strip
Cam is supposed to be from Bob Mazzolini’s shop.
What springs do you think I need ???
What do you think of this combo ?
