Does this prove David Vizard's 128 lsa formula ?

This whole cam selection formula thing from DV has sparked my interest, maybe I might try it for the next engine I do. I want get more engine performance books, maybe I might pick up DV's How to Build Horsepower book.:)

If you have an engine you want a cam spec’d for let me know bore, stroke, rod length, compression ratio and at what RPM you want to make peak torque and I’ll run some numbers.

I can’t tell you exactly what the numbers might be because it sometimes throws out some crazy numbers.
