355ci horsepower?

Its hard to say without compression ratio, heads, cam, ignition, and the like, but I had a 355 putting out about 370-400 at the crank. This is roughly 300 at the wheels. I had the Edelbrock RPM Airgap, 10.5 compression, Comp Extreme Energy Cam, and worked 2.02 heads. I also had a pertronix second strike ignition system. If you have similar stuff you can expect about the same, although you carb might be a little to big for such a combo, bigger is not always better.

well its got 64cc heads, lunati roller cam and lifters, roller rockers, 9.8 compression, and 2.02 intake and 1.60 exhaust valves.

285 at 4500 rpm 317 at 5000 rpm 348 at 5500 rpm 380 at 6000 rmp Depends on what rpm band your testing at ... Sounds nice good luck
