Re: Z28 Pulley question
Hi guy's,I have pulled both a '72 and'73 original Z-28 apart and both (to my surprice) had 3942456 "DV" pulley's which according to the '73 Ass'y. manual is correct.Why would GM go from "DV" in '69 to a 060 "AP" in '70 and then go back to a "DV" in '72-3?
To what I remember all the Sm. Dia. pulley's,824's,060's and 847's(replacement') were BB only.Along with '69 only 640's. Would a Yenko Nova use a "AP" or a "DV"? Just trying to understand what I have seen.Joe.
