LS Cam tests are popular as hell and for good reason. Everyone wants to know what kind of power increase they can see with certain cam specs, and Richard Holdener has possibly done more cam testing on LS engines than anyone else. I say this because I’ve personally been with him testing dozens of cams and have seen pallets of camshafts come to the dyno shop for him to test.
For Richard, this 6 cam test could have been done before lunch.
Check out this variety of camshafts being put through their paces to see which one is the best in this 5.3 LS.
Video Description:
HOW MUCH POWER IS A CAM SWAP WORTH? HOW CAN I IMPROVE POWER ON MY LS? WILL A MILD CAM ADD POWER DOWN LOW? HOW IMPORTANT IS CAM DURATION? WITH THE HECK IS CAM BIGNESS? IS THE SLOPY STAGE 2 CAM THE BEST CAM EVER? DOES ELGINE MAKE DIFFERENT CAMS THAN THE SLOPPY STAGE 2? CHECK OUT THIS VIDEO WHERE I COMPARED TWO ELGIN CAMS TO THE STOCK 5.3L L33 CAM AND THE FAMOUS SLOPPY STAGE 2 CAM. I ALSO TOSSED IN A PAIR OF BTR CAMS, THE TRUCK NORRIS AND THE NEW HOT ROD CAM FOR GOOD MEASURE. SPOILER ALERT-SMALLER CAMS MAKE MORE LOW SPEED TORQUE AND BIGGER CAMS MAKE MORE TOP-END HP!
Thanks for an awesome session. It’s fantastic to be able to see the actual numbers that result from these swaps
Thank you for doing these,
