Oil slosh
And that costs not only a few rpm but slower rpm up the scale and horsepower!
Don’t run extra oil in regular cars. A lot of guys add 1 quart to there race rides. Is that OK.... that is debateable...
The best and proper way?
Extra capacity oil pan.
AutoXCuda has worked with Milodon on the road race lane set ups for the small block.
A little pricey but well well worth it!
