They idle great, ones in pops boat surge pretty heavy with the 41 props on. It keeps you on your toes.
Doug already went thru the fuel system. Hatches will need modification.
Seem reliable so far, probably got 30 pulls and zero leakage. Even a couple extended pulls to piss off the neighbors.
Doug doesnt want to announce the numbers till its finished

Ive never heard of a motor that has zero leak down.How do you do that?

Total Seal Rings will get you close.

Yes they will. If I see one of mine over 3-4%, I get concerned.
What do you know about Total Seals Keith???
Eddie

These have a .017 dykes ring

Seem reliable so far, probably got 30 pulls and zero leakage.

O leakage ?????? do you mean fluid leakage Shawn ???

Yup! That's what I run.

Maybe I should have clarified, no leakage issue to speak of, 2 percent or less.
The pro mod stuff goes 8-10 cold normally, course we dont worry about leaking much with them as long as the majority of the piston is still in the hole

Aren't you running SPEED PRO RINGS BIG Daddy ? or did you switch while she's apart this time ?

any new info on the dyno pulls yet Shawn?
