When you want to make more power with your LS engine, there are not shortage of bolt on parts that will help you reach your power goals. Camshafts, heads, intakes, all the normal performance parts you would throw at any engine will make some real power gains when combined with the power packed LS platform. But what are the best bolt-ons for an LS3 or L92? What gives the biggest bang for the buck? Which performance parts are going to give you the most? Cam swaps will ALWAYS pay off with one of these engines, but cylinder heads can be good too. How good though?
WHAT ARE THE BEST BOLT-ON MODS FOR A 6.2L LS3 OR L92? WHEN IT COMES TO AN LS, ESPECIALLY AS LS3 OR L92, THE ANSWER IS ALWAYS A CAM SWAP! ACTUALLY, THE ANSWER IS ALWAYS BOOST, BUT FOR AN NA LS3 OR L92 MOTOR, THE BEST POWER GAINS CAN BE HAD FROM A GOOD CAMSHAFT. CHECK OUT THIS VIDEO ON WHAT HAPPENS WHEN WE APPLIED A COUPLE OF DIFFERENT CNC-PORTED HEADS AND TWO DIFFERENT CAMS TO THE LS3 CRATE MOTOR (THNX GANDRUD CHEVROLET). ALSO CHECK OUT A SIMPLE CAM (AND VALVE SPRING) UPGRADE ON A USED 6.2L L92 COMBO (WE REPLACED THE VVT). DO CAMS REALLY WORK? YOU BET!
