When selecting your camshaft, please keep in mind that the largest camshaft you can run on a factory LS2 or LS3 short-block is our 231/236, .641"/.615", 112 LSA camshaft!  Anything larger will require you to cut valve reliefs in your pistons!  Our 229/236 and 231/236 camshafts were designed on a SuperFlow 902 engine dyno on a factory LS3 engine.  These camshafts are designed for maximum power on a stock LS2 or LS3 short-block without any piston-to-valve clearance issues.
 
**You must have a minimum of a 4.00" bore size to run the L92 cylinder heads!**
