HP Rating? Need help
I have a 72 Nova and I am trying to figure out what my HP rating is. Here is what I got:
1. 350 Chevy bored .30 over (355 CI)
2. Weiand Stealth Intake: idle to 6800 rpm, dual plane
3. 750cfm Holley Street Carb
4. Dart Iron Eagle Heads 200cc intake runner, 64cc chamber, straight plug, 2.02”/1.60” valve job.
5. Comp Camshaft: 480 lift, int/exh 280 adv dur
6. Headman Headers: 1 5/8inch, 3in collector
7. 2500rpm stall converter
8. 3.90 geared rear-end, limited slip
9. MSD 6A Ignition System w/8.8mm plug wires
10. Compression Ratio: approx 9.5-10 to 1
Can anyone give me an idea of approx HP I might be pushing?
Thanks
Mike Bowden

going with my gut, it says somewhere around 375. Alot will depend on the full cam specs, it could go either way. Do you have any 1/4 mile times?

bought the car about 3 months ago. I just recently looked up ser#, etc... to verify exactly what kind of heads, carb, etc. I had. the camshaft info was located in the glove box, plus the car lot I bought it from told me some basic stuff the Nova had in it. Is there a free eng analysis program out there u can download to get HP figures?
thanks

Run it on a chassis dyno, then there's no guessing. Excellent way to work on the engine tune, too.Yesterday is history, tomorrow is a mystery, Live for Today!

clarification: I am saying 375 flywheel.
If you do have some ET's, or perhapse it would be worth getting some, you can plug them in here for an estimate. It will only be as good as runs though..

This is what I got using Desk Top Dyno, assuming free flowing mufflers, hyd lifters, and 9.5 - 1 comp, this would be flywheel hp
Good guess un-sane

For sure!! I recall Jim's torsion bar suspension on at least one of his builds, but I'm not sure which one! Maybe the Track T?? He's a talented builder.
