Guest JAMIE T Posted May 26, 2005 Share Posted May 26, 2005 I just picked my head up from my head guy. I had him re-flow it after doing the valve job. So, here go's in CFM. INTAKE EXHAUST .100" 98 82 .200" 168 134 .300" 219 190 .400" 262 208 .500" 268 221 He suspects the transition from round(throttle body) to actual port shape(the shape of the port as it is in the head) is a flow restriction. Maybe I'll build a manifold for it and put a Q45 throttle body on it. I'll eliminate the round ports altogether. Quote Link to comment Share on other sites More sharing options...
