Too much cam… is that a thing? Well, it might be in some instances, but what about in your junkyard 5.3? I know I’m looking to swap a 5.3 into a square-body Suburban before too long and I want it to be a daily drivable light-duty town rig so I want more power than the stock 5.3 provides, but it certainly isn’t going to be a race car. I bring this up, because I watch all these cam test videos from Richard in order to make an educated decision on which camshaft will be right for my own project, and want you to do the same thing for your project.

Video Description:

CAN A CAM BE TOO BIG FOR YOUR MOTOR? WILL A BIGGER CAM ALWAYS MAKE MORE POWER? CAN YOU RUN THE WRONG CAM? IS BIGGER REALLY BETTER? WILL I ALWAYS SACRIFICE POWER WITH A CAM SWAP? WHAT CAM SHOULD I RUN IN MY 5.3L LS? CHECK OUT THIS VIDEO WHERE I RAN FOUR DIFFERENT SIZE CAMS ON AN ALL-ALUMINUM 5.3L L33, STEPPING UP IN SIZE FROM THE STOCK L33 CAM. HOW MUCH POWER DID THE TRUCK NORRIS MAKE OVER THE STOCK CAM? HOW WELL DID THE MILD TRUCK NORRIS COMPARE TO THE BIGGER HOT ROD AND RED HOT CAMS? DESPITE BEING DESIGNED FOR THE LS3, THE HOT ROD AND RED HOT CAMS MADE GOOD POWER ON THE 5.3L, BUT DID WE REACH A TIPPING POINT WITH THE 5.3L?
