GT Transformation
The jump in boost pressure upped the power output from 559 hp to a whopping 613 hp. The peak torque was up as well, from 513 lb-ft to 545 lb-ft.

Project ’47: Part Two
The Blueprint 383 provides the Advanced Design pickup with nearly 400 hp and 442 lb-ft of torque, which is plenty of power for cruising, especially the fair- grounds. During the engine build, Blueprint Engines took the time to photograph the machining process, as the company completely refurbished the Chevy four-bolt main block, machined and assembled it into a brand new horsepower monster.

Re-Rigging For Aesthetics
When someone buys a boat as a bare hull and finishes it themselves, the odds are that the boat won’t be nearly as sanitary as the original manufacturer rigged it. The original owner of this boat did a decent job but it was no way up to the usual Howard standards. The owner wanted the rigging cleaned up, spiffed up and colored up so he took it to Maveric Marine in Van Nuys, California where Dan Duffin straightened everything out and color-coordinated the powdercoating.

DJM Engineers a Leveling Kit for the 2007 Tahoe

The ’07 Tahoe, Chevrolet’s premature baby, hit the street in late March 2006. Introducing the next generation of Tahoes so early was part of some master marketing scheme, born and nurtured in the hallowed halls of Chevrolet corporate. In any case, the ’07 Tahoe’s rear ride height measured 23-1/8 inches from the center of the hub to the lip of the fenderwell, while the front measured only 20-1/4 inches. As usual, the rear stood considerably higher than the front.
For those who don’t see this suspension configuration as “cool,” DJM Suspension of Gardena, California, a manufacturer of suspension lowering kits, immediately set to work engineering a leveling kit to put the “ass-end” of the ’07 Tahoe on the same plane as the front. In other words, DJM engineered a cool-looking kit.
The DJM leveling kit features 2-inch rear drop springs, for which the installation is rather straightforward.
After the wheels are removed, the lower shock mounts are unbolted. The sway bar is then unbolted but not removed. The rubber isolators are removed and saved to be re-installed. The 2-inch rear drop springs are then installed. When the springs are securely in place, the lower shock mount is rebolted. The sway bar is then retightened in place.
At the completion of the DJM leveling kit installation, the rear had been brought down exactly 2 inches and its ride height measured 21-1/8 inches. The installation of the DJM leveling kit made all the difference in the world to the stance of the ’07 Tahoe.
The accompanying photos follow the highlights of the teardown of the stock suspension and the installation of the DJM lowering springs. Check it out if you are looking for that cool stance on your new Tahoe.
