In a street car build with a stock engine, with stock clearances, stock tolerances etc. that will never see over 6500-7000rpm, I just can't find a good enough reason to justify my customers needing to spend nearly 150-200 dollars more on an oil pump when a ported LS6 or stock LS6 has done the job for so many for so long.

Since we're on the topic of pumps and since I just recently witnessed what happens when you fail to check, I want to mention that the clearance between the timing chain and pump should ALWAYS be checked, especially with double rollers. Even with the spacers and the little dimple that the Mellings have, they will still make contact and contaminate the engine with aluminum shavings.

I agree. The Mellings are nice pumps, but there really doesn't seem to be any significant benefit to running them over the standard LS6 pumps on an engine with tight clearances (ie stock).
