I know that the only way to really find out is on a dyno but I'm a little ways from there right now.
Here's my setup

383 stroker motor, block from an old c10
400 crankshaft
about 10:1 compression
comp's Magnum CL12-326-4 combined with 1.6 rocker arms (.515 lift)
aluminum l98 heads ported and polished
doug's full length headers
aluminum edelbrock victory jr intake manifold
edelbrock 750cfm carb....................

As for the rest of the drivetrain....
2800 lockup stall (may go higher)
700r4 trans with transgo shift kit and corvette servo (saving up for a full rebuild soon)
10 bolt with richmond 3.73 gears and auburn limited slip......

any input is appreciated!!!!
