Ok, on my long rod build sittin on the stand.
Bore- 3.445
Stroke- 4.125
Rod Length- 7.005
I don't know about peak RPM power, but the camshaft grind I chose is .495/
[email protected] on a 108. FWIW, static compression is 10.5. I know dynamic will be around 8.5, but this is with the closed chamber head and flat tops with one valve trough and I can get "around" .027" quench distance. I ain't skeered to go down that far, because my red line will be 6K at the absolute most and it'll likely never see that.
