Sorry 3712 cam. I picked up the cam used and ran it in my 403, still looks good. It has eded 371 stamped in the back plus 901562, I believe plus a 17 cast in the front on the shaft. I just picked up a 76 350 to run it in. Shim head gaskets and have a Cloyes Street roller timing set which I plan running in the advanced position. It also has a D9 that flashed at 1800 rpm, 2004r and 3.42 gears.
