HOT SWAP
It’s no secret that the GMs LS-based small blocks are great performing engines that are super reliable. As far as an out the crate, or junkyard, option is concerned, they are hard to beat for bang for buck. However, there is always room for improvement; improvements that won’t break the bank but will unlock a few extra ponies hidden within — all without the need to remove the heads. While the normal swag of bolt-ons will net you a nice little gain, a cam swap is really going to awaken the beast within. We’ve teamed up with Kelford Cams and will be using one of their CNC ground bump sticks for the example.
Deciding on the perfect cam for your application can be a little tricky, and it’s not something we’re going to get into here, as it is a whole topic on its own. Instead, we recommend you speak to the experts in making your decision — that’s what we did. For our otherwise stock LS1 that is going to be slotted into a cruiser with an auto and stock converter, we opted for the Kelford 108-D, which is by no means their wildest profile but shouldn’t give us any dramas with the likes of vacuum. But, as we said, talk to the experts. The team at Kelford will be happy to assist you in making your decision.
WHAT YOU’LL NEED
Along with swapping in the cam there are a few other items you’ll want to replace at the same time. Some are simply preventative maintenance
