Thumpr! lol. I used to love the Dual Energy series, but everyone else shunned them, preferring the Xtreme Energy cams (but not so much the noisy rockers!). Serious builds I tried to use the High Lift .904 series or the Purple Plus .904 series, depending on what the app needed. I just haven't needed a Thumpr yet but I know they run good and sound mean. I did get one ground on a 113* LSA for a Buick 455, but I haven't run it yet. Perfect specs as far as duration split, but the Buick likes that wide lobe sep on the street with stock heads.
i got a hell of a deal on it, figure if it dont work i can pull it out and get racerbrown to re grind it to something that will, but i like big lopey cams and ant skeerd to turn rpms to get the power band!
