ZZP's GT camshafts currently hold all the horsepower and ET records for naturally aspirated L36s. Anytime you upgrade the camshaft from the stock one, we highly recommend running either Comp Cams or Crow Cams 105# valve spring, or the very common LS 90 lb valve spring, along with ZZP Modified retainers, LS7 lifters, 7.00" pushrods, and you can either run the stock timing chain with a new replacement dampener or the best option is the Rollmaster double timing chain, Extra thick front cover gasket, and Machined oil pump cover. However all of these upgrades are not always required, they are just a very good combo that works very well together.

The GT1 cam was designed for naturally aspirated applications where emissions and street-ability are important. It will generally 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. The GT1 can be used on stock heads with stock springs and retainers but upgrade to 90 or 105s is recommended along with higher shift points.

Look for gains of 30+ HP depending on your car's current configuration with a drop of 1/2 sec in the 1/4 mile.

  • 210°/210° at .050"
  • Intake Lift .317" (.507" lift at 1.6:1 rocker ratio)
  • Exhaust Lift .317" (.507" lift at 1.6:1 rocker ratio)
  • 113 LSA
The GT2 cam was designed for NA applications with maximum HP in higher rpms. It is recommended to upgrade the valve springs (125# or higher), modified retainers, and LS7 lifters. It has a lopey idle and performs best with a higher stall speed torque converter. 

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 40 HP depending on your car's current configuration.

  • 216°/216° at .050"
  • Intake Lift .317" (.507" lift at 1.6:1 rocker ratio)
  • Exhaust Lift .317" (.507" lift at 1.6:1 rocker ratio)
  • 111 LSA

Gt-1 cam

I give this a 5 star because it really improves my cars performance by 30 hp and a bit of torque I would really recommend it, you will feel a difference in power when launching

Have had this cam in my car for well over a year, and I love it. A very aggressive sound for a V6!

2nd times the charm?

Considering this is my second cam in less then 10000 miles after a motor rebuild due to a hydraulic lifter exploded....

Good parts

All parts fit as described and woke my car up. Had to do a security relearn but no instructions could be found on site. Found the on a forum. Other then that I like it all very much.

I just wanted small gains for my daily driven '05 Bonneville SE. The sound from this cam is very good. I like the slight lope to it. Torque is improved quite a bit along the entire spectrum. I installed this with the ZZP HV3 insert. Great combo. Thanks guys, works perfect! Next mod, High Velocity TB and spacer. Should see some gains and better responsiveness.
