HP Estimate?

I have a 360 SBC that im putting in my street stock. i was just wondering if i could get a HP/TQ estimate, and possibly if i should change my cam and intake.

350 SBC bored .60 over.

Edelbrock Torker 2 intake

Holley 650 cfm carb

11:1 comp.

Crane Energizer 302. .500" lift, 246 degrees duration@.050". 106 lsa

full roller rockers (cant remember ratio)

1 3/4 headers, 3" exhaust from header, about 2 ft long, to gutted glasspacks.

Heads are '66 Camel Hump 2.02/1.60, fully ported, screw in studs.

Im thinking about getting a Victor Jr. or equal intake, and an Isky 284 mega cam. is that a good idea? im wanting to step down in duration a bit because i think 246@.050" is a bit to much for it.

Thanks.

You should be in the 375 hp range with 400 ftlbs.

Your weak link is the cylinder heads and intake manifold. Get a set of ARF's and a performer rpm intake and pick up 50 hp!

Trash the glasspacks.

Your cam duration is not that much. However, it all depends on car weight, diff gears, transmision, and convertor you are using.

I ran a setup like that with 200cc dart iron eagle heads, rpm intake, 750 Holley, 5 speed trans, 3.90 gear, in a 2950 lb car. It ran 120 in the 1/4 mile and 135 with 150 hp N20.

Carb's OK

The carb's good for 500HP easy, so it's ok in a 360 pushing about 400+HP. The cam's ok enough, because your compression is at 11-to-1 anyway. The heads are perfect. In fact, the engine could easily take adavantage of a cam with .550-.570" lift and 250 degrees duration at .05" inch lift for closer to 450-470HP.
