As our pal Richard Holdener will tell you, the LS engine takes to cam swaps like a toddler to candy.
Problem is, swapping a camshaft on an LS engine is a pretty cumbersome process—especially when it’s installed in a vehicle. That’s because to get access to the cam, the timing cover has to come completely off, which means the harmonic balancer and crank pulley have to come off, which means the front accessory drive has to come off, which means…well, you get the idea.
The good news is, with this two-piece timing cover design from Edelbrock, you’ll only have to do that job once. After that, the harmonic balancer can stay put, saving you a ton of hassle.

As an added bonus, this design means you won’t have to remove your oil pan (or risk breaking the oil pan seal) either. Just pop the top of the cover off and voilĂ , you can get to the timing gear and camshaft without a whole lot of teardown.
Sound good? Edelbrock makes these covers for both the Gen. III and Gen. IV LS engine. Click the part numbers below for more details, pricing, and availability:
Extraordinary claims and all that – are the folks from the private equity roll-up’s PR department not able to provide a pic of a camshaft halfway out of the block with the balancer still in place to prove their claims?
Or are they saying it works because some engines might have an aftermarket smaller-diameter harmonic balancer, so that makes it technically true?
