Dave...Was it the bearing shells that did not transfer the combustion heat to the coolant system via the main webs??I wouldn't lose a minutes sleep fretting over this. A racing engine designed to live at high rpm continuously is a much different animal, with much different design criteria than your street motor driven occasionally at the strip. Especially with short stroke motors there is no concern for us with strength as the overlap cross sections between the rods and mains on a short stroke motor isn't an issue for anything short of an all out racing motor. I've run cross drilled 302, 331 sbc motor for years with no issues and they see more than an occasional 8000 + rpm burst.
I have burned up a good 331 in 30 minutes time due to insufficient heat transfer at the rods. The crank turned blue on the rod and main journals when the heat from the combustion chamber transferred just fine down the piston into the rod but couldn't transfer into the main webs to be carried away by the coolant. So it just sits there getting hotter and hotter until the oil breaks down and the crank is destroyed. But the problem wasn't with the lube system.
He does offer a good reason to continue to run the higher oil pressures keeping in mind the 10 psi per 1000 rpm consideration. For a sbc the Z28 high pressure spring works well for this.
This is probably good advise for those running long stroke motors on the edge that will see heavy loads and high rpms, but I wouldn't hesitate to use one for a street or street/strip car.
I should know better but maybe I am misunderstanding the wrong use of the term cross crilled crank.All cranks have one hole. The cross drilled cranks have two.
