"What cam should I use on my build?" - we hear this question all the time.
Our standard answer: "It depends."
But there's a very good chance that a Leineweber cam will make you smile. Just saying!

Caution!!

May cause intense fun, arms pulling off the handlebars, lack of rear tire tread.

L51- Pan/Shovel cam for 90"+ engines, pairs well with Speed and Science heads, hydraulic lifters.
Complimented by clean fuel and air!
