lifter galley crossover tube
The galleys were joined together to eliminate the velocity issues and to even out the pressures in the system. Now the oil can better make the turns to the mains.
The engineering you speak of is never settled. Engines are always being refined.
Yes my engine lost the 2&4 mains because of the grooved cam. To my knowledge none of the major cam manufacturers groove those cam journals because the failures have been documented.
All aftermarket race blocks now use priority main oiling.
Nothing is oiled from the main bearings except the cam bearings and
The rods and certainly no flooding of the lifter bores.
You are offering old outdated information by advising people to cross drill there crankshaft. Absolutely no crank manufacturers offer this any more. Allmost all race crankshafts now use straight shot oiling holes right to the rod journals.
I offer the following pages from recent performance publications.
Cross drilling is now viewed as detrimental to rod oiling of which you claim to improve because centrifugal force inside the main journal throws all the oil to the main bearing and the oil does not make the turn inside the crankshaft to the rod journal passage.
The best advise you could have given the OP was to read very thoroughly Guitar Jones oiling mods thread. There is enough in there for everyone New and experienced to learn something.
The oil pumps on the New Chevy and the New Hemi are driven off the crankshaft to eliminate the failure prone intermediate shafts that occasionally break at high volumes and pressures.
