Relative to the oiling in the Cleveland, there are a few mods that make the engine sing.
I have cranked my Boss 351 to 9100 RPMs ( with a few Hail Marys ). If you are interested in the changes I made, pm me.

BTW, if you are looking for someone to do your engine, Brent does a excellent job.
Just my $0.02 worth.
