Project Novakane Part VII: Parts You Need To Make Your LS-Equipped Truck Go Fast

We like to be the custom truck guinea pig for you. Whether it be making mistakes during an install, getting so close to finishing a project only to need extra parts, or even buying the wrong parts when we thought they would work, we like to help you know the ins and outs of an install before you crack open the toolbox. When it came time to drop in the GM Performance Parts LSX376 engine into our Project Novakane '04 GMC Sierra, we quickly learned that swapping a high-performance engine where a factory 4.8L once resided wasn't as easy as just bolting it in place.

Ideally, you pull the 275hp engine out, bolt in the 750-plus-hp engine and begin the recreation of Eleanor's last stand in "Gone in 60 Seconds." However, once real life kicks in and you're elbow deep under the hood, you realize that an engine capable of 750 hp needs high-performance parts, and you also learn that there are differences between an LS-based Vortec V-8 that was designed more than 10 years ago and a newer LS3 engine that is one of GM's best ever small-blocks. Here in this story you'll learn what we learned, but without wasting all of the extra money like we had to do. A valuable resource we found when tracking down our engine parts was Summit Racing. Known for go-fast, hot-rod parts, Summit also carries a full line of OE parts that you would typically find at a parts' store. Rather than drive to the store, only to find out the part was out of stock or a special order item, we stayed home and ordered them from summitracing.com. If you're considering pulling your worn-out LS-engine out of your '99-and-newer Chevy or GMC and swapping a high-performance crate engine, here are some important parts to secure before you turn a single wrench.
