Sounds about average to me, as long as it runs good.

The stock maf is only 74mm, the stock tb is bigger then that so at higher hp levells the factory maf becomes a restriction, I like the other oem delphi 85mm maf, offers improved flow with an opening that is bigger then the throttle body.

Our old 383 with an LS6, 85 maf, ported stock TB and the Ms3 it made in the 440-450 range. With a Fast 92, and 90 TB it gained about 20HP-25HP.

Your #'s look good. The cam makes good top end power. Mine felt very lazy below 5000rpm's Even with a 3600 stall and 4.11's

With a 100 shot it should run high 10's with traction and supporting mods.

seem a little low. I have the same mods as you but the stock 241 heads and I made 412rwhp through a 4.10, 10 bolt. After my nitrous tune (went from 28* of timing, down to 21*) I made 400rwhp even.

100 shot is 517rwhp.
