LS cam swaps are nothing new, but they can still be a little mysterious. In this Tech Talk, we run through a 5.3 LS cam swap on our LM7 junkyard engine with a BTR Truck Norris Camshaft and demonstrate how you can do a cam swap at home.

Adding this BTR Truck Norris Cam to your Vortec 4.8, 5.3, or 6.0 is as straightforward as any other LS cam swap. This swap is well worth the time and effort to upgrade the cam in an LM7, L59, or any other variation of LS truck engine.

GM’s LS engine platform reaches across most of the General’s lineup of vehicles. However, it’s most common in Vortec powered V8 pickup trucks from Chevrolet and GMC. With so many of these trucks on the road they have become a great source for LS swap fodder for everything from classic muscle cars to hot rods and trucks.
