The higher the grip level is the more time you need to spend on helping it keep oil where it belongs. A oil pan with good baffling (I'm a fan of the Autokraft pan), accusump, oil cooler, and good venting on the valve covers and valley through a catch can.

Thanks Tim. Completely agree with the handling statement and will add brakes to that. With the new generation crate powerplants it's an uncomforting thought wondering what type of chassis' they may be going in.....and the fact that they could be coming at you on public roads in a manner similar to a Skud missile.
One the the better tracks near us (6 hours) is Thunderhill and T2 is an oil starver for sure. It's a pure 180*3rd gear radius that's probably damaged more than it's share of motors.
The GMPP LS3 525 motor is what I've been looking at as a decent target for the shop to improve on by addressing the oiling and venting issues along with insuring the motor gets adequate fuel, that should deliver a reliable cost effective package in my amature mind at least.
At what point does the Nodular Iron crankshaft/rods/pistons become a weak link in an LS?
