Enough to run some decent et's in a well sorted chassis? Who cares what hp # it makes, what does the car weigh and what does it run?

The car is a base hard top 02 z28 so probably around 3400 with a 4000 stall and 3.73 gears

If it made 465 I’d be tickled I’m hoping at least 425.

I have a similar set up, but haven't had
mine dyno'd either. I'm going to guess 430-440 rwhp.

depends on the dyno, how good the converter is, if it's locked/unlocked

Probably low 400's.

377*7000/3456=(X)*.069 = (Y) * 10 = (BHP) * .85 = 447RWHP

447 at 7k if there are no exhaust or intake restrictions at sea level around 80*F ambient through a 4l60e on typical tires on a dynojet with pump fuel 93 no additives
