hi, 300 CFM will be too much for what he needs. i attended a super flow seminar, years ago, mr betts, statement was, do not get hung up on big flow numbers, port velocity and port shape are everything. faster moving air will fill cylinder faster than a big number with low velocity. higher port velocity, gives you better throttle response, more torque. torque is what moves car.granted, you do need more flow, but not at a loss of velocity. just food for thought.
