Thanks for some specks.I guess the effciency of the combustion chamber is the reason behind the timming being low.Just think what he could do with a motor for the Hot Rod Mag Pump Gas drags in Memphis Tn.Theres some pretty stout #'s there runing on socalled pump gas:D

some one should get Tim to jump on here and keep us informed sounds like a hell of a motor i am not sure about that high of rpm for marine use
Mike I wonder with the Fast could he get it to Idle very low? I would think at 7k + rpm it would considered to be a hot poker run motor or a race motor.

That seat pressure is almost enough for a hyd. roller camshaft. NO where near enough for a mech. roller

Tim is claiming 900 rpm idle with very little if any blower roll.

Yes on the valve weights also no lifters or pushrods.
