Here it goes. I recently took my rebuilt 360 in the car for a dyno test and to say in the least I was somewhat disappointed in the results. Horsepower at the rear wheels was 153.6 and the torque was at 250 lbs. From talking to a expert in the engine rebuilding, this engine should have done much better on the test. The 360 is overbored by 30 using standard compression pistons, an Isky cam (not sure of the model number right now), and sidepipes simialiar to the trendsetters (the generic type). According to the expert, it is most likely the Isky cam that was installed. The Isky cam was designed along the lines of GM specs and there is good chance that the engine is not accepting this setup. Not accepting this setup, the net gain is dramatic horsepower lost.
Any comments are welcomed and I should have known that I should have installed a Erson cam in the first place. (have a Erson cam in the 390 AMX and have yeilded outstanding results from it).
