I don't have a flat tapped but used Lucas 30wt. Got a 2.5 gallon jug of it. Seemed like the rings seated on the first drive.
This is just a cam change... engine has about 850
miles on it but the tight LSA didnt like the EFI
or should I say it the other way around
Mike,
Why didn't you go with a wider LSA roller grind? I know there isn't much to choose from in the catalogs, but if I find one that suits the combination, but has a tight LSA, I'll call them and have one ground wider. Comp can usually turn one of these around in a couple weeks, and then the lobe failure worries go away. Just a thought, since you are already set up for a roller.
