fully ported aftermarket TPI can make power to 6000rpms or so on a 305 probly with a big cam. maybe even on a 350.
recent TPI shoot out had a 383 maintaining a flat HP curve past 5000rpms to 6000+rpms and had a small peak at around 6000rpms. the cam was big tho and its obvious the TPI was holding back the airflow

JerryWho is shifting his TPI around 6200rpm and has turned a 12.59 in the quarter. With my A4 I have it set up to shift around 6000 in the 1-2 shift. Will be going to the track this Saturday to see how she does. Allen
