Stumbled across this link for engine suffix codes for Chevy SB and BB and some misc Mustang info. Anybody seen this before? No reference provided that I could see. Decent one stop shopping, if it is accurate. I ran a couple #'s that I knew and they checked out. The subject line caught my attention under BB. Some other interesting ones in there too.
