Why not call Bert’s and ask Steve about the engine? I have an engine from them with all of the neat stuff you mentioned. Pretty sure you have a stock oil system.
I rotated them about 4000 miles back. I’m hoping to get 20K miles out of ‘em, but that’s just a guess. I’m wondering how this is comparing to anyone else running the American Classics. I really don’t know how long these have been on the market.
9,600 miles on these American Classics on a ‘29 Tudor. I was running 38 PSI but noticed the centers are wearing more than the outsides. Dropped down to 35 PSI and will monitor wear.
