Hey guys. I've got a 69 Mach One with 4500 miles on the 377 stroker engine. It is noisy. I have a b303 cam shaft with an Eagle Specialty Products rotating assembly. I am currently using Valvoline 20w-50 Racing Oil. My oil pressure raised when I changed to this oil, I was using Kendall GT-1 20W-50 oil before. I stopped by Kragen and saw the Lucas Oil additive and claimed that it quieted engine noise. Does this stuff really work?
