I punched the data into Desktop Dyno and it has you making 400 horsepower @ 5500 RPMs, 413 torque @ 4500 RPMs. The numbers might be slightly more but I didn't have the cam file so I had to punch in the numbers. Also, I wasn't sure what type of cam this is hydraulic, solid etc... so I used a solid lifter cam. I also used 2.02/1.60 valves because I believe those are the valves in the Edelbrock RPM heads correct?

Car Test says
0-60: 4.2
0-100: 9.9
1/4: 12.5@115.8
Granted- those aren't truley realistic numbers. It's a "ball park"
That was done on stock 1977 Vette spec with a 4 speed and a 3.70 rear. 255/60/15 tires.
