Camshaft upgrades and LS engines go together like jam, cream and scones. Whether you simply want more chop or genuine power gains, a cam upgrade is practically a must-have.

That’s why in this episode of Carnage, Scotty walks us through what it takes to dial in a big stick for an LS engine. We should note this example is right at the top end of the performance spectrum, as he’s installing the cam into our 427ci Dart LS Next block.

This thing is going to have two turbos hanging off the side, with intention to eventually run seven-second passes. It’s being installed in our wicked VS Commodore ute; you’ll find more of the build series here.

Scotty ordered a very large, boost-specific hydraulic-roller cam from Crow Cams. He’s not dealing out the full specs, but let’s just say it was a tight squeeze into the block.

Dialling in the a cam is important, as it’s needed to make sure the timing is bang-on. There’s a few ways to do this, with Scotty opting for the piston-stop method.

Using a Proflow degree wheel and a dial gauge on top of piston number one, Scotty was able to read the position of the camshaft in relation to the piston hitting top dead centre.

It’s a fiddly and time-consuming process, but necessary to do the job like right. Once the cam is sorted, we’ve got top-tier Johnson lifters to go in, a trunnion upgrade to install in the rockers, and a bunch more work. For now, check out the episode below and get schooled on camshaft installation:
