Mixed in with the dizzying array of Gen 6 Camaros in the Chevrolet booth is a handsome but innocuous-looking 1970 Camaro RS. The classic Camaro serves as a reminder of the muscle car’s storied history, but it’s also a convenient place to display Chevrolet Performance’s new LT4 crate engine.

Even though it’s the motivational force behind the Corvette Z06, the LT4 isn’t all that exciting on a stand by itself. So, Chevrolet Performance shoehorned it into a 1970 Camaro RS, to help whet the appetites and imaginations of hot rodders who’d be happy to find a use for the most powerful production car engine GM has ever produced. The crate LT4 can be used in custom cars, street rods, trucks and just about any other application that the imagination can come up with. It’s available as a dry- or wet-sump engine, and Chevrolet Performance offers air conditioning and accessory drive kits for a range of applications.

Will any of them be more attractive than this Gen 2 Camaro RS, though? The challenge has been made!

Chevrolet Performance has given the 1970 Camaro RS concept several visual links to the latest Camaro. Most noticeable is the Hyper Blue Metallic paint with white rally stripes. The color is new to the 2016 Camaro, and the color scheme is shared with the 2016 Camaro Hyper concept displayed a short distance away. LED lighting is a subtle upgrade that modernizes the 1970 Camaro RS. Less subtle are the 19-inch wheels, which contribute a distinctive resto-mod look that hints at real-world performance.


Interior modifications look subtle at first glance, but are comprehensive. The seats are actually from a Gen 3 Camaro, re-trimmed to match. The custom leather-wrapped instrument panel features a unique cluster with updated gauges to monitor engine performance. A six-point roll cage has also been installed.

The roll cage is there for a reason. This particular 1970 Camaro RS is packing a 6.2 liter supercharged V8 rated at 650 horsepower and 650 pound-feet of torque. The LT4 crate engine is a serious piece of hardware. It’s been upgraded with aluminum cylinder heads, titanium intake valves and upgraded forged aluminum pistons to handle the additional pressure generated by the supercharger. Chevrolet performance also offers an engine controller for manual transmission applications. The SEMA Camaro RS puts the power to the ground with a six-speed manual transmission.

This classic Camaro’s chassis has undergone a substantial revision as well. To handle the additional power, the suspension gets coil-overs at all four corners and rack and pinion steering. The rear has been upgraded to a four-link setup. The larger wheels make the installation of Corvette Z06-based disc brakes on the front and rear possible. This 45 year-old Camaro is likely to exhibit performance on par with the 2016 model.

SEMA is all about getting involved in the personalization of your car, and Chevrolet Performance backs that up nicely. This 1970 Camaro RS sports a modern engine and drivetrain that can be easily applied to a wide range of classic vehicles, offering enthusiasts the chance to take their own cars to the next level. It’s always satisfying that a manufacturer’s gearhead spirit extends beyond simply trying to sell new cars. (It doesn’t hurt that the Gen 2 Camaro is my favorite, either!)

Press Release

Chevrolet Performance is showing off the new LT4 crate engine in the most attractive way possible – under the hood of a classic 1970 Camaro RS. The concept vehicle was introduced today at the SEMA Show, in Las Vegas.

As the supercharged 6.2L heart of the Corvette Z06, the LT4 is rated at 650 horsepower and 650 lb-ft of torque, making it the most powerful production-vehicle engine ever from General Motors. The new crate engine – offered in dry-sump and wet-sump versions – allows builders to use the high-tech performance engine in their hot rod projects.

This Camaro concept uses the wet-sump kit, along with complementing air conditioning and front-end accessory drive kits.

“Chevrolet Performance pioneered the concept of high-performance crate engines and the LT4 represents a new threshold in technologically advanced, production-based choices for builders,” said Jim Campbell, Chevrolet U.S. vice president of Performance Vehicles and Motorsports. “Whether it’s in a classic Camaro, like this resto-mod concept, or a vintage truck or street rod, the possibilities are almost endless – and that’s exactly how we continue to fuel the dreams of enthusiasts.”

In addition to the LT4 crate engine, the Camaro features a T-56 Super Magnum six-speed manual transmission.

To harness the power of the supercharged powertrain, the concept’s chassis and suspension systems have been upgraded with an independent front suspension with coil-overs and a rack-and-pinion steering system, as well as a four-link rear suspension, also with coil-overs. It rides on a set of 19-inch polished aluminum wheels and stops with the assistance of Corvette Z06-based front and rear disc brake kits developed as upgrades for the Stingray.

A blend of design cues inspired by the all-new 2016 Camaro complements the contemporary powertrain that drives the vintage muscle car, starting with the Hyper Blue Metallic exterior color. It’s one of the available colors on the Gen Six Camaro and it’s accented with white rally stripes – just like the 2016 Camaro Hyper concept on display at the SEMA Show.

The exterior also features LED headlamps and taillamps, as additional nods to 21st century technology.

Inside, the black, stock-appearing cabin features custom-trimmed seats from a third-generation Camaro and a custom instrument cluster with new gauges that work with the powertrain’s electronic systems. The instrument panel itself is wrapped in custom-trimmed leather. There’s also a six-point roll cage for added protection.

About the LT4 crate engine

The LT4 is based on the same Gen V small block architecture as the LT1 engine used in the Corvette Stingray and 2016 Camaro SS, with several unique features designed to support its higher output and the greater cylinder pressures created by forced induction. They include Rotacast A356T6 aluminum cylinder heads that are stronger and handle heat better than conventional castings, lightweight titanium intake valves and stronger forged aluminum pistons.

Chevrolet Performance offers the LT4 with wet-sump (part number 19332702) or dry-sump (part number 19332702) oiling packages. Front-end accessory drive systems are offered for both applications, along with an air conditioning kit and a power-steering kit (wet sump only).

An engine controller –part number 19331517 – is available for manual transmission applications. A custom control system must be used for automatic applications.
