So does the A9 = 360hp upgrade? If it does, and with this MW block (rather than MZ that the factory built 179 were), it could one of the few that got the 360 add-ons in the trunk for dealer install. What throws me is 2 Rochester 4bbl carbs rather than Carter, Offenhauser intake, and finned alum air cleaner rather than the round chrome dual snorkel correct one... Pics of the car will not help at this point.
