I am sure this has already been brought up and beat to death but I haven't found it...
I picked up a 70 390 and I am trying to figure out what front cover is on it. It's just getting broke in (75 miles or so) and I am not having any problems but concerned. Any way to tell if it is factory, crown, Bulltear (hopefully). If crown how to identify good or bad or if it is working it is good?
THanks
