True but this NASCAR cars are made to do 9500 RPM the Gen 2 5.0 can barely do 8000 RPM. As I said my engine is running as it should but it's losing oil I will know more when my dealer check it on Friday.This last weekend a NASCAR Cup car over revved. They changed the valve springs and raced it the next day. Engine lived. I know our cars are not meant to last at those engine speeds. My point it to share that the part(s) they saw as most effected were the valve springs.
