race oil and how much?

I'm changing fluids on our B/PS '04 Corvette and would like to try some race oil. The engine, other than the cam and springs, is completely stock (55,000 miles). What would be a good race oil for the LS1 and how many quarts should I run? The stock capacity is 6 quarts and I've always used Mobil 1 per factory recommendations when we drove it on the street. Now that we trailer it and only race is there ET to be gained? Thanks for any advice.

I'd keep using Mobil 1, considering the stock bottom end

i would try 5w20 mobil 1 synthetic 5 qts vs 6 to see if it makes a difference. There isn't much to be gained due to the crankshaft and oil pan design.

Thanks, I can do that. Every little bit helps. I appreciate the advice!

Just have to make sure you don't clog the cat converter with an oil that has too many off road additives

We are lucky with our engines. Any full synthetic works great..!

Two reasons:
Roller Lifters and Stock spring Pressure.
Which means a lot for reliability.

There maybe a hundredth or 2 between brands.

Amen brother! No worries ... that's the next move. Wonder if she'll be offended if I get her a helmet for our anniversary? She knows that the 130+ lbs. lighter that she is will be worth more than a tenth!!!
