The Competition cams GT cams are designed for use in naturally aspirated applications. ZZP's GT camshafts currently hold all the horsepower and ET records for naturally aspirated L36s.
The GT1 cam was designed for naturally aspirated applications where emissions and street-ability are important. It will not set SES lights. The GT cam uses steep ramp rates and tight base lobes to keep the computer and the sniffer happy while still providing great performance. This cam does not set the P0300 code and can be installed on a stock 3800 all the way to radical. It was designed for the NA L36 but will also work well with nitrous or intercooled boost. It is the only major L36 grind on the market that does not need a converter or gear changes to see gains.
Look for gains of 20-30 HP depending on your car's current configuration with a drop of 1/2 sec in the 1/4 mile.

The GT2 cam was designed for use with totally stock heads. Stock springs, keepers, retainer, lifters and pushrods can be used. Upgraded pushrods are recommended but not needed. RPMs past 6200 will require upgraded springs. Either 90 or 105# springs are recommended for high RPM use. Click here for GT2 sound clip
This cam was designed for naturally aspirated applications where maximizing the performance of stock heads is important. It will set the P0300 code unless programmed out of the PCM. Idle is lumpy, especially with headers. Raised shift points (6500), raised rev limiter (7k), and gears/converter are all recommended.
Look for gains of 25-35 HP depending on your car's current configuration.

The GT3 cam was designed for use with ported heads and added displacement. Upgraded pushrods are recommended. For use with stock heads mod'd retainers are required.
This cam was designed for naturally aspirated applications using our stroker kit. For use on a highly modified 3.8 liter, shift points will need to be 6800 - 7k for maximizing the powerband. It will set the P0300 code unless programmed out of the PCM. Idle is lumpy, especially with headers. Gears and a higher stall torque converter are recommended.
Look for gains of 30-40 HP depending on your car's current configuration.

Keith Handlon's Camaro:-
Using our Comp Cams GT cam, Keith has dyno'd a best of 220WHP.
The GT cam helped him go from a PB of 14.72 (stock cam) to 13.79 with our GT cam
