Being brand spanking new to this BB I was wondering if the topic of racing has a home here? I drag race using a Methanol injected 555cid BBC. Being forced to change from my Dino Kendall 20W-50 has been forced upon me and could use some help in picking the best non synthetic oil available. Don't want to get off on the wrong foot with the syn crowd here it's just an economic reason for running that type oil. any help?
