That would make it 660 cfm, which about what I was told. Dave Layer told me my LT2 SS engine would be done about 8200 due to the throttle body restriction. It falls off a cliff about 8300 on the dyno. The 305" TPI cars have the same size, if I remember correctly (been a couple of years now.) Dave said the 305"s run right up to 8800/9000. Hope I remember the numbers correctly.
