Why would 7250 be a problem with a 80mm stroke engine? I run mine to 7500 regularly with no issues. Hell, one of Culberro's rally cars hung out at 8000 for minutes on end. Piston speed is way too low to be a problem.

For added reference, a Honda K24 can and does see 8000 RPM no problem with a damn near 100 mm stroke.

Rotating mass should not be an issue either because a) your rotating mass isn't that heavy and b) see paragraph above.
