Add hotter cam or Add hotter head ?
Nah won't need a dyno ..because the question was which one would move it down the quarter mile faster, cam or better head "in its existing form w/ exh manifolds"
Cam it and access the tiny 175 cfm but still be limited by the gear n convertor ..
or
have near 200 cfm peak intake by the stock max lift...stretch the power band with the better flowing exh port and support it with more spring...meanwhile also raising the compression..umph in the low end/part throttle...more a/f =power.
