A set of Dart 215's or similar heads that will flow somewhere close to 250cfm at .550" valve lift on the intake and his guess would then be closer to correct.
I was estimating around the 400 mark.....
What di you think about a set of ported Sportsman II on same combo....?
Also, that cam seems big....
