how high can i rev my 383
I'm ready to fire up the 383 for the first time, I'd know to know what chip to put in the MSD rev limiter. It an 87 L98. scat 9000 crank, TRW rods, Keith Black 10.75 CR pistons, heavily ported L98 heads, 2.02 intake and 1.8 exhaust i think. !.5 rockers, 590 lift cam, not sure on the duration. edelbrock performer rpm intake, and 770 holley street avenger.

If you're worried about the crank or rods, you'll be good to 7000 rpm easily. In your set up, the pistons are your weakest link and rpms don't affect them as much, so a conservative estimate is 6500 rpms. Double check the camshaft/rod bolt clearance before you crank it, I built one twice.
