thanks for that info. I was not sure the 165 darts flow well or not.

Vinnie, according to the Dart catalog the Iron Eagle SS's flow 221 cfm at .400" lift on the intake, 136 cfm at .400" lift on the exhaust, 232/138 at .500" lift, so intake flow is comparable to GM vortecs, but, like GM vortecs, the exhaust is rather poor in flow compared to the intakes. With an exhaust flow of 61.5% of intake flow a split pattern cam would be very helpful. The 180cc and larger port Iron Eagles have a much better exhaust/intake flow ratio. They're around 70-71%.
