Crazyhorse will run a Desktop dyno on my motor for me and see what you come up with. The specs are:
548 ci
355 canfileds Intake flow:[email protected]
[email protected]
Exhaust [email protected]
[email protected]
Cam profile symmetrical [email protected] I&E
.655 Lift I&E
L/S 114
C/l 112
Procharged with 12 lbs of boost at 6000 RPM, intercooled and fuel injected. Static compression is 9:1.

If you need anything else let me know, just trying to get a rough idea.

Fred, here it it. I had to use seat-to-seat timing numbers because that's the way the spec card was printed. The other two sims were both at .050 lift.

jspeeddemon, I took several liberties with your engine specifications, so if you spot any big errors I'll be glad to rerun the sim for you. DD2000 didn't have the procharger listed so I used a Vortec.

The .006 lift specs on the comp cam tend to make the comparisons an "apples to oranges" kind of deal as compared to .050 lift when you're looking at the projected numbers. If I get time I'll go back and find the .006 timing specs for the other cams. I'll run this one too.
