What would your guess be? Any good power adders that wont break the bank? Thanks guys!!Supernova!

Here's a bunch of dyno tests on small block Chevys, see if you can find one close to your combination....

Hp on a mild small block?
one thing you can do is get bigger chambered heads and match your headers to the head

Buy David Vizard's book on nitrous, read it and put a 100 HP shot on it. It will increase your torque by 200 lb/ft. @ 2626 RPM and go down to a 100 lb/ft increase @ 5252 RPM.
Have you tuned the vacuum secondary on your 600 Holley? Look at Holley part numbers 20-59 and 20-13. They are about $25 total and will let you tune the secondary side of your Holley.
But, you really should try the nitrous. Your quarter times will be about 1 full second and 10 MPH faster. It's better than sex.

i havent tuned the vac secondary. I was actually considering on the holley street avenger 670 cfm carb as an upgrade. That nitrous squeeze is tempting but would my stock 9.5 pistons and seals survive that blast consistently?!Supernova!
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
