camshaft timing?? right or off a tooth
#12
Also with it a tooth off the cranking compression would be higher or lower than the other motor depending on which way it is off because the intake closing would would happen way sooner or later

I thought that I would have to reprop also. The old engine and drive set up ( no box and 1 1/8 lower ) turned 5400 RPM ( 650 HP with 1.5 to 1 and a 28 pitch 4 blade Bravo prop ) 6000 RPM with the drive ratio at 1.5 to 1.
With the new engine and box I now turn the same prop at 6100 RPM
I just bought a new BBlades labbed Bravo 4 blade 28 pitch modded for my boat.
