It's a 395 cfm Carter carb from a 62 318...Power Pack I think. Offy intake. Anything else is as he bought it but not sure what was done by PO. Nothing else in the car has been touched that I know of.
Fair enough. It would have been interesting to know if the intake (including carb) were mainly what was it holding back.
A '65 has a decent weight advantage and a smaller frontal area over both a 67 and 74.
