I just wanted to point out not to overlook the importance of the engine oil to be warm enough to work well.

This links shows an oil cooler installation on a Camaro SS. I should think the same could be applied to a Corvette. He installed a thermostat in his system.

I know its lubricating ability wont change because of the weight, only its flow characteristics, as you stated, which would decrease the time it would take for the oil to get up to temp since its going to move faster, or so ive been taught. Especially if you're not driving the car. I know any time i take mine out i let it warm up, but thats me.
