Like it says in the title, in my opinion, one of the best cam guru's around, U.D. Harold can make magic with steel hands down. Fast closing ramps yet controlled, and I make a ton of power with my UD cam. 505cuin's in my 3600 lb camino runs 9.80's on motor alone, 10.5 tire and a glide, need I say more??? They gave me exactly what I wanted for power in an engine. Call Bullet Cams as they baught Ultradyne out and talk to Tim Goolsby, he was U.D. Harold's grinder from way back.
