Can someone run these numbers

If someone could desk top dyno my new egine I would be very greatful. I am running 10.5 to 1 TRW pistons on a 355. I have the corvette/Z28 double hump heads with the 2.02 intake vavles and comp cam rocker arms with roler tips. I am running a 274H extreme energy comp cam. It has a .487/.490 lift. On top I am putting on a AIR GAP RPM intake with a holley 750 double pumper with mechanical secondaries. All of this is fired by a mallory unilight electronic distributor. Exhaust exits with hooker competition headers. I hope this thing makes good power.

:confused:

Cylinder heads. Iron will be fine, but you need flow. Dart, AFR or W/P Sportsman.
My engine has about 350 HP according to DD.

I get 422HP if you switch to a set of Sportsman II's with the same specs. You could also get your heads ported. What valves are in the heads you have? I ran the numbers based on 1.94/1.50. Also, I got the same base numbers as 1979toy. Is your car an auto or a stick? Gears? That is a big cam you have there.

O.K. This time I get:

381HP@5500
398LB@4500

If you switch to a single plane with that cam you get:

405HP@5500-6000
402LB@4000

You loose about 30LBs at 2000 tho. You never mentioned if you had a stick or an auto. With that cam and an auto you would definetly need a high stall converter.
