The engine data is entered and I went through the on-line Comp Cams catalog for lobe grinds. There are three for an overhead cam engine with direct acting lifters and 1.1 inch wide buckets. #9013 has 0.410 lift and 226 duration at .050, #9014 has 0.420 lift at 232 duration at .050, and #9015 has 0.430 lift at 238 duration at 0.050.
The cam timing optimization options were used in the filling-emptying model. The best combination is a moderate lift #9014 lobe for intake and a higher lift #9015 for exhaust with a 110 degree lobe centerline. This equates to 107 crank HP or 96 rear wheel HP.
The need for a higher lift exhaust cam makes me think the exhaust valves may be too small. Tomorrow evening the wave action model will be used to look at mach numbers.
The intake flow data I entered was for the head, manifold, carb, and air cleaner at 28 inches. Then, I also calculated and entered the carb restriction based on 10 inches. A call was made to tech support. I thought I was entering the carb loss twice. They said I was and the flow data should be for the head and manifold, only. Fortunately I have that and it will be entered later this evening.
The program has a feature to look for optimum cam timing for any fixed lift value. I wanted to figure out optimum lift. The tech support guy says that is too hard to program. Flow and HP tend to get better with more lift and there is no way to set a realistic ceiling. He said to look at the physical limits of the valve train, durability, and affordability to figure out maximize lift, then to optimize the cam timing for that lift.
