470 low deck

If the oil system is done correctly, Chrysler oiling is good to atleast 340 in the seat and almost 900 over the nose at 8500 plus.
Believe what you want. I speak from personal experiance, 22 years running Jesel rockers, spraybars, then pushrod oiling when i had to. Do yoy really want to risk a total rebuild when you get to a certain level? I will not again. The motor worked great at 225 on the seat, then at 300 on the seat i had a motor contaminated with burnt steel. Not cheap.
