Comp Cams Camquest

To get some kind of estimate for the power level in my engine, I toyed with Comp Cams Camquest page. I entered the requested parameters and the app spat this kind of graph for me:


Calculated peak HP was about 260 @ 5000 RPM and peak torque 330 @ 3500 RPM. This was using all the stock parts like carburetor, intake manifold, exhaust manifolds etc.

To get some kind of idea which parts would have the largest effect on the engine, I went through some of the options one by one. Better intake and bigger carb added about 25 HP and 10 ft-lbs but changing the original exhaust manifolds to headers gave a huge 50 HP and 35 ft-lbs boost!


Combining the intake and carb with the headers brought in another 30 HP and 10 ft-lbs. If the Camquest simulation is even close to real life results, I think first item on my upgrade list would be the headers. But for now, I'll go with the stock parts.
