I have a print out from NHRA that has manifold part#'s. There is no listing for the 273 4bbl. The 273 4bbl intake for the '65 has a different bolt pattern than the later years. The intakes runners are lower on the intake manifold than the superceded 302 head. The difference at the top of the port are significant and disturbs the gas/air flow from the intake to the head. I would like to use the late model intake from a 4 bbl 318 motor that the 302 was mated. Thanks
