LS Swap Hedder & Motor Mount Kits for Iconic GM Muscle

Hedman Husler Hedders has been known for decades as the industry's premier high performance hedder manufacturer, and BRP Hot Rods is an LS engine swap authority. The two performance "gurus" have joined forces to create "MUSCLE RODS" LS Engine Swap Kits that contain practically everything you will need to drop an LS Series engine into a variety of early muscle car chassis. Each Muscle Rod Kit comes with a set of quality Hedman Husler hedders, frame and motor mounts, transmission crossmember and transmission mount. Since all the parts were developed as a kit, they eliminate the "trial and error" headaches generated by parts that are not designed to work together.

Aside from 70-81 F-Body Camaros and Firebirds, 78-87 G-Body Monte Carlos, 64-72 A-Body Goats, Chevelles and Cutlass', and 83-99 S10s, Muscle Rod LSX Kits like this one (part #55902) fit 1st Gen Camaros and Firebirds. This 1st Gen Camaro kit contains a set of 1-3/4" tube Hedman Husler Hedders that have stout 3/8" thick head flanges to provide a long lasting, non-warping seal, and a gasketless style ball and socket collector. This particular kit's hedders have Hedman's HTC Ceramic-metallic coating, but they are also available uncoated. The kit's frame and engine mounts are rebuildable, and are manufactured using 1/4" cold-rolled steel plate. Urethane bushings, grade 8 bolts and all-metal locknuts come with the kit for a secure mount. The crossmember is compatible with 4L60 and T-56 transmissions, and also includes a durable urethane bushing and mounting hardware. Finally, all metal engine and transmission mount components are 007 silver powder coated for a long lasting clean look.

The kit is designed to maintain the factory recommended 3 to 5º (degree) pinion angle using factory front accessories, and will work with OEM oil pans (exact pan will vary between applications). To help save even more time, no frame notching is required to clear popular Sanderson A/C compressors, if KWIK Kit bracketry is used. It is this attention to the details, and the use of off-the-shelf parts that make Muscle Rod Kits so invaluable to gearheads looking to perform the LSX swap. The superior quality of All MUSCLE ROD Kits is so reliable, they are backed by a lifetime warranty.

XFI SPR Cams & Phaser Limiter Kit For GM Gen IV VVT Engines

Rather than find ways around the recent advances in GM engine technology, engineers at COMP Cams have found a way to work with the innovation to produce a powerful line of cams for the newer L92 engines. This new series of XFI SPR (Valve Springs & Phaser Modifications Required) Camshafts features four unique cam grinds that each provide substantial gains in both torque and horsepower.

The 2007 and newer GM L92 engines utilize Variable Valve Timing (VVT) technology, which changes the timing of the valves while the engine is in operation. VVT is controlled via cam phasers, which are computer controlled cam gears that automatically optimize camshaft timing based on the current engine rpm. While this technology provides tremendous efficiency benefits, it presents a challenge when designing performance camshafts. This is due to the wide range of valve timing movement which causes piston-to-valve clearance.

As a result, the COMP Cams engineers have developed a Cam Phaser Limiter Kit (Part #5456) that restricts the range of cam timing movement from 50 degrees to 20 degrees. While still utilizing the efficiency benefits of the VVT technology, this modification provides the necessary valve clearance for larger, more serious performance camshafts with tighter lobe separations. The resulting increases in upper-rpm horsepower (70+ hp) from a simple camshaft swap are some of the largest ever seen by valve train experts at COMP Cams, and these gains occur without any sacrifice to bottom-end or mid-range performance.

These new performance camshafts are designed for use with the COMP Cams Phaser Limiter Kit (#5456) and Beehive Valve Springs (#26918).
