As far as oils go, Joe Gibbs for me but some of the others are good as well, comes down to personal preference/experience. If Keith Craft swears by Joe Gibbs then that's all I need to know. It's going in a DART aluminum 427w race block. I'm using it in my BMW K1200S sportbike, 11.5:1 cr, runs like a champ.
