Is it any wonder that a guy who calls himself SuperShaft is such an expert on DP'ing?

Hell, if I set up a racing engine I would reverse offset the piston bores Smokey style for closely related reasons. It does work! But I would long rod one too. That works big time again for closely related reasons. It's granted that generally larger displacements have more detonation issues because flame front travel times remain relatively constant despite displacement but there are still advantages to be had there in a 750 IMO as well as many others but to each there own.
