I've heard about 17 alleadged L72 1967 "fat cars" but have never seen proof.If they did exist what would they use for a tach? There is only two tachs available for a 67(5500redline for a L36/427 and 5000redline for everything else 396 and smallblocks).Also IF they were COPO's where in the GM inventory would they get a L72.The COPO system as far as I know used "existing" parts in its inventory and routed them to assembly plants not normally used as rpo's and necessary assembly components(unless they mismatched 427/435hp and 396/375hp components together?)This is a mindbender as the L72 was avaiable in 66 and 68 but not in ANYTHING in 1967.My head hurts, where's my meds?
