I'm trying to put together a plan for a 66 or 67 Valiant drag car. I'm trying to decide on what engine displacement I should go with. I would like to run Super Gas (money allowing), but would settle for something slower. Whatever the class, I would like to run in the low 10s to mid 9s. Should I stick with a sb that I can wind higher or should I go with a bb with more torque and hp?
