Full Tilt
It's no doubt the LS-series engines are a true out-of-the-box performer. The LS motors seem to share almost bulletproof qualities in the rotating and valvetrain assembly. When it comes to all-out drag or open track racing though, stiffening up the rocker-arm flex and stabilizing those actions is critical. Comp Cams' trunion upgrade is a direct OEM replacement with stiffer, more durable 8620 steel alloy. Needle bearings are replaced with caged roller bearings to increase rigidity, and they comply with drag racing classes where stock components are mandated.

Six Equals Eight
Wringing out power from the Camaro's new direct-injected V-6 is cake. It already spits out 300 hp from the factory and runs consistent 14-sec time slips. However, the power-hungry techs at Zex have designed a full nitrous system that turns the six cylinders into eight with the flick of a switch and stab at the throttle. Operating safely was a must, and with Active Fuel Control, the system automatically adjusts fuel delivery with changes in bottle pressure. The system will only activate under wide open throttle and is adjustable from 55 to 100 additional ponies.

Borgeson's steering conversion kit will make your sled a bit quicker by trimming up to 28 pounds from the front end while also unleashing parasitic loss in the accessories drive. The kit comes with a GM 525 steering box, a pitman arm, and a half-rag joint to connect to the stock column. All kits are built in the USA and come with a three-year warranty.

Gear Spread
Supporting up to 850 hp in a six-speed is not easy. Somehow TCI has managed to squeeze more gears, longevity, and user-friendliness into a super package for the street or strip. The six forward gears (2.97, 2.31, 1.57, 1.18, 1.00, 0.75) are fully programmable and allow for quicker acceleration and increased fuel economy. A paddle shifter is optional for manual mode-gear selection. The 4L80E case is coated for cooler operating temps and is self-contained, which all but eliminates problems with external bolt-on overdrives. The complete TCI drivetrain package includes the transmission, control unit, paddle shift, wiring harness, cooler, and dipstick.

Monster flow
Getting the most flow out of your big-block cylinder heads is easy. How does a 339cc intake port or even a 376cc runner sound? RHS designed these 24-degree heads with the all-out drag racer in mind. The 339cc intake valves are 2.250 inches, while the 376cc versions come with 2.300. They share 1.880-inch exhaust valves, multiangle intakes, and radiused exhaust valve seats for added flow. For maximum atomization and velocity, both intake and exhaust ports are CNC-ported, as are the 121cc combustion chambers, which eliminates improper port-to-chamber transitions. Hotspots that occur in the chambers are all but eliminated through a refined path in the water jackets.
