piston questions

Well, I am too but I won’t give up what the RPM will do for the cost difference. The rpm is better at every point in the graph. They match in a few spots but the m1 is never better and in some places the rpm is 20lb/ft better. And that was on a 350hp ish engine. On more engine the gain will be more. The list goes like this;

Best to worst
1. RPM Air gap 365/423
2. M1 dual plane 350/400
3. China gap. I’ll have to look for the numbers.

i think johnny mac reported that the stroker motors were down a good amount with the knock off. but, stroker motor...

your point is valid, though. power is power.

however i think it's a viable alternative for a low HP application where budget is a concern. is it the right choice, no. but given there aren't any real alternatives that's the best choice in that particular situation.
