Summit Racing sells Brad Penn oil. Purchased plenty from them. I prefer Brad Penn conventional 30 SAE for my 505 big block mopar engine with a Bullet flat tappet cam. I was told by Crower Cams tech line to not run synthetic oil with flat tappet cams. I run the Crower cool face EDM hole solid lifters. Works great, no issues. I have considered running Joe Gibbs oil also. It is all expensive stuff.
