Should work for any small block from 1970 up until the time they switched to the serpentine drive. Would work on the earlier engines but the inlet from the radiator is on the wrong side & the snout is longer so the pulleys won't line up unless you switch all of the pulleys on your engine to the 70 & later style. Also the radiator hosse will hide the timing marks on the earlier engines.
