if you like i can run it though an dynamism and see what it might be making but i would need to know your Exhaust and Intake type along with what your carb is and what its CFM is

This was the perfect "street-strip" cam combo in my opinion, as it idled nicely at 850 rpm and sounded mild for its level of performance. A 2500 rpm converter is all you need for good street manners (if you have an automatic). I used 1.6 ratio rockers for a lift of .595".
Vacuum was about 12-13" at idle and I had no problems with headlights or brakes. I tried different carbs.....750 Edelbrock, 800 Edelbrock, and 825 Mighty Demon. They all worked well with the best performance and horsepower from the 825 Demon. I used an RPM Air Gap intake.
Rear wheel HP was 373, and with 4.11 rear gears ran an 11.62 E.T. in my '69 coupe.

I ran this exact combination on my previous 383. My AFR 195's were before the Eliminators, but were the competition ported ones so specs were similar but yours will perform slightly better.

you just made me smile with the last part of your post...
i have that cam going into my engine that im building, afr eliminators, stealth intake, forged internals, 9.8 c/r... i was worried that the cam wouldnt have the kick i needed, but im very happy with your numbers, and being that im aiming for a 12sec 1/4 mile it just makes it that much better.
