Best cam for oval dirt track racing on 10.8 springs
Fantastic cam!! Easy instal, zero clearance issues, easy to time, the power is amazing compared to stock. Add in some 18+ lb valve springs ang the billet flywheel... better hold on to your butts. My neighbors won’t bring their pocket rockets out anymore when they see the Sundae Chopper out. No complaints so far. Great product.
This plus a few other mods turned our karts into a completely different animal! Its a neat feeling to rock the throttle and the kart snap your head back like your in a drag car, LOL!
