WOW, if you are throwing down that kind of $$$. the builder should have went with a dry-sump...a turbo buick can use the high psi/volume oil at hi-rpm. plus you can add a oil accumulator for first time start-up. this will let you pressurize the oil system before and during start-up..(you will find it in a alot of pro-mods).once the engine fire-up the belt drive pump will take-over with engine oil pressure and re-pressurize the oil accumulator canister. If production cars came with this feature. the engine will likly do a 1,000,000 mile before dieing or cloging it self from cabon build-up, but regular oil change can reduce that.
i like the extreme edition to your truck...
