Old Tele Man, that was probably doing pretty good since your engine was probably turning over 3000. With my camshaft retarded 2 notches, the power stroke did not end until almost bottom dead center, and the intake valve stayed open till the piston was almost half way up. The displacement was twice the original (almost) so full throttle did not make it ping because of the Atkinson cycle effect (expansion stroke was much larger than the compression stroke). Mine was a gentle low power engine that operated in the 10 horsepower range.
