GBody Shuffle

Are your ’86-’87 GN wheels looking a little ragged these days? Owners of our favorite late-model Buick musclecar can now rejoice, thanks to our friends over at Gbody Parts. Not long ago, they released a one-piece aluminum wheel the replaces your heavy, two-piece OEM ’86-’87 GN unit. Available in 15x7, -8, and -10-inch widths, the wheels not only drop considerable amount of weight from your stockers, but will allow for wider tire widths as well. When compared to the 15x7-inch chrome plated steelies, the Gbody Parts’ aluminum versions of the same size are 10.6-lbs. lighter—each! Being polished aluminum, they obviously won’t pit or rust, either. Backspacing for these are based on wheel widths, so if you want to simply replace your stock-sized wheels, then your backspacing remains the same at 3.75 inch. Eight-inch and ten-inch wide rollers require a backspacing of 4 inch and 4.5 inch, respectively. As a bonus, the center cap is mounted to the center of the wheel, so you no longer have to worry about losing one going to your local car show or track day!

ZL1 Shaft

Are you looking for a way to drop rotating mass out of your 5th-Gen Camaro’s drivetrain? Then look look no further than this one-piece aluminum driveshaft from Livernois Motorsports & Engineering. This 3.5-inch unit will not only take some unnecessary weight out of your Camaro, but it will free up some of the 15 percent of horsepower and torque drivetrain loss you typically lose when incorporating the OEM two-piece steel driveshaft. As such the Livernois driveshaft will give you higher horsepower and torque numbers when used on the dyno, street, or track. Livernois claims that this one-piece aluminum lightweight can handle the abuse that a 1,000 hp, 4,000-lb. 5th-Gen can throw at it! It bolts right into your stock driveshaft’s mounting locations, and will work on both automatic, and manual versions of today’s Chevy pony car.

Air Corvette

Yes, we know, the C7 Stingray is out in full force and is all the rage in late model ’Vettes these days. But that just means that the older C5 Corvettes are much more affordable, and therefore, finding new owners. Those new owners are going to need new speed parts, and AIRAID understands this. With 345-405 hp on tap from a factory C5, power was never really a problem for the aging Corvette, but more is never a bad thing. AIRAID claims that their brand new C5 kit adds as much as 21 hp right out of the box without tuning. It eliminates the most restrictive sections of the OEM intake system, and provides a cleaner and updated look. AIRAID’s C5 kit is available in both standard ABS plastic, and carbon fiber. It’s a direct bot-on for owners of ’01-’04 Corvettes, but for those with a ’97-’00 model, you’ll have to pick up the later style mass-airflow sensor. So if your looking for quick and easy bolt-on horsepower for your C5, give AIRAID a call.

Designed for any new Gen-IV LS engine with a 4.000-inch, or larger, overbore, these splayed valve 6-bolt cylinder heads use a 2.165-inch intake and 1.600-inch exhaust valve with a 68cc combustion chamber standard.

Twin-Turbo Time

Proving that the 4th-Gen crowd refuses to refute to the power of today’s Camaro, the aftermarket remains viable for these throwbacks. Granatelli Motorsports gets it, and they just launched this twin turbo system for ’98-’02 LS1-powered Camaros and Firebirds. On mediocre 91-octane West Coast fuel, it pumped out 450 rwhp with a stock LS1, on a beginner’s level 7-psi. tune. For those looking for something a bit more impressive, and put those pesky Nissan GT-Rs in their place, you can tune it for up to 1,100 hp with a professionally built engine. Granatelli also managed 815 rwhp on a low compression 427 LSX engine, at 15-psi. on 91-octane. The kit is of OEM quality, and comes 100% complete with everything you’ll need to put some serious power down, including twin 62/66mm PTE T3/T4-housed turbos, twin 38 mm TiAL MVS wastegates (to scare imports, obviously), GMS/TiAL 50mm compressor bypass valve, and stainless steel exhaust components throughout the entire system. You might want to invest in a 12-bolt or a 9-inch rearend first, though.

Mack Daddy

A 900hp crate engine!? Yes, please! Lingenfelter Performance Engineering, better known as LPE, has recently cooked up this killer engine combo. Being heavily vested in the late-model EFI GM performance contingent since the beginning, LPE knows their way around a GM LS-series engine. This particular entry, comes to you, assembled, in a crate, with a 3.6L Kenne Bell supercharger strapped to its forged short-block, LS9 heads, and all-new GT22 camshaft-equipped powerplant. LPE sells crate engines, ranging in power output of 500-900 hp, and this particular dynamo will fit in anything from street rods to the C6 ZR1. The beauty part is that this killer engine package is designed and built to be completely reliable in a street application. Can we get a 900 hp daily-driver? Apparently with shops like LPE, it’s possible. Now we just need to figure out how to shove one under the cowl of a 4th-Gen.
