The wait is over. GM Performance Parts announced today that their crate motor production for LSX engines would be starting with two combinations. The 376 will be their budget engine and the LSX 454 being the all out LSX bad boy.

The world is an imperfect place. No matter how hard we try, the things we make are always going to be just a little bit different than we want them to be. Normally, it’s just something we have to live with – “good enough” usually is, and a few thousandths of an inch doesn’t make a difference.
A deep look inside the baddest piece of hardware ever to come out of the GM stables – the LS9 Supercharged engine going into the Z06 Corvette. Can you say 600+ hp of LS anger with OEM reliability? We can…
When you upgrade your engine to make a substantial increase in horsepower, it goes without saying you also need to upgrade your oil system. Many people think of their oil pan and oiling system only after they have spent thousands of dollars on go-fast parts.

Ever since we first realized that putting a bunch of lead into the air wasn’t such a great idea back in the late 60’s, there’s been an ongoing struggle between efforts to protect the environment and the quest for more speed.

Coatings do great things – anything from keeping heat out, engine items lubricated, and parts looking good. Tech Line Coatings has released a line of professional and do-it-yourself coatings that allow you to cost-effectively coat parts with little to no prior knowledge.

As you may faintly remember from biology class, evolution is a change in the inherited traits from one generation to the next. In the automotive ecosystem, designs evolve the same way living things do, with only the fittest designs withstanding the test of time.
Fastest Street Car’s LS-Wonder Camaro is a typical LS1-powered automatic SS with bolt-on’s. It made 309 rear wheel horsepower with under drive pulleys, exhaust, cold-air, and a tune. However, we were looking for more, beyond the nitrous we had been squeezing at the track.
A camshaft is the brain of your engine. It tells the engine the proper time to breathe in, when to exhale and keeps the spark plugs firing on queue. Picking the wrong cam is like having a couch potato enter a marathon. The wrong application just isn’t going to work properly.
Nobody likes paying for insurance, but when it comes time to file a claim, everyone is relieved that they have it. The same could be said about coatings. Some don’t like putting out the money for what they mistakenly believe to be a nonessential luxury.
Show parts aren’t looked upon as performance pieces under a lot of circumstances. Billet Specialties is one of the exceptions. They have added another line to their front drive systems for LS-based engines and we are going to install one on a GM LS3 crate engine.
Restricting the use of zinc and phosphorus in motor oils had an immediate impact on gearheads like us. Camshafts began failing at an alarming rate. Lobes on new camshafts were getting wiped quicker than Kanye West could interrupt an acceptance speech.
Rocker arms are the nervous system of push rod engines: They transmit the camshaft impulses received to the valves, opening them at precisely the right moment hundreds of times every minute. These important engine parts represent some of the best horsepower-per-dollar gains possible, and they are also easy to swap
We were excited when JE Pistons announced that they were going to be applying their massive knowledge of piston technology to take their existing affordable budget SRP piston and upgrade into the more beefy SRP Professional line.
COMP Cams’ new Ultra Pro Magnum Rocker Arms are engineering works of art. Just one look at the redesigned version of the very popular Pro Magnum line of rocker arms shows the ingenious thought process behind the rocker arm’s design.
Scorpion Racing Products has produced the ultimate piece of engine candy, the seemingly everlasting Racing Lifter. We were invited behind the walls of the Scorpion Performance Factory which looks and operates more like a watch factory than an engine components manufacturer.
From a practical perspective, going to a machine shop is like going to a marriage counselor. Seriously, and we’re not trying to be funny here, but there is a relationship between what your goals are and what your pocketbook and equipment can produce.

When you hear the words “505 horsepower, 0-60 in 3.7 seconds, and 11.7 seconds through the 1320…”, only a few cars come to mind that fit into this super car category – we must be talking about the Corvette Z06!

We wanted to know if the performance of an “out of the showroom” Corvette could be improved by adding one of the most common upgrades that engine builders start with: a new intake. After some research, we selected an intake from VaraRam. VaraRam’s VR-SCI Gen 2, better known as the “Snake Charmer.”
