LOVE IT! I have the 3.7L I5. Its rated at 242HP. I'm content with its power, although I feel GM should've slapped the LL8 into it if they could've. I've added a K&N CAI and it helped alot, especially at higher rpms. I highly recommend the truck. Its very fun to drive. Although it gets about the same mileage as the VX. If you do buy an H3 try to stay away from the 06' model year. the 2006's had the 3.5L at 220HP and customers complained it was a dog with that engine. Not to mention some were known to have cylinder misfires. If you have the cash get an Alpha. Another bonus is that you can fit 35's under the wheel wells with very minimal TB adjust.
