340 cam specs?
I am helping a friend with a 1973 340 mopar. The factory 340 camshaft spec is .429 intake and .444 exhaust. The NHRA blueprint spec is .462 and .473. Does anyone know if this is a typo or are we missing something? We hate to have a cam made that is incorrect. We compared a simular vintage Chevrolet 350 and the spec of .390 .410 is the same both factory and NHRA.
