1970 Chevy Camaro RS LT4-01

Chevrolet Performance is using a novel way to show off its new LT4 crate engine, by putting it under the hood of a classic 1970 Camaro RS at the 2015 SEMA show in Las Vegas.

As the supercharged 6.2 litre heart of today’s Corvette Z06, the LT4 is rated at 650 hp and 881 Nm of torque, making it the most powerful production-vehicle engine ever from GM. The new crate engine – offered in dry- and wet-sump versions – allows DIY builders to use the big V8 in their hot rod projects.

This Camaro RS uses the wet-sump kit, along with air con and front-end accessory drive kits. The gearbox is a T-56 Super Magnum six-speed manual.

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 aluminium pistons.

“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. 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,” said Jim Campbell, Chevrolet US VP of performance vehicles and motorsports.

To handle the young stable of horses, the classic muscle car’s chassis has 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 modern-looking 19-inch polished aluminium five-spoke wheels and stops with Corvette Z06-based front and rear disc brake kits. LED headlamps and taillamps are additional nods to 21st century technology. Looks fantastic in Hyper Blue Metallic with white rally stripes, don’t you think?

Inside, the cabin features custom-trimmed seats from a third-gen Camaro and a custom instrument cluster with new gauges that work with the powertrain’s electronics. There’s also a six-point roll cage for added protection.
