It’s a minor miracle Denny Terzich Jr.’s head isn’t about 10 times larger than it is. After all of the ego-massaging he got over his 1956 Chevy—the one that won Goodguy’s 2002 Street Machine of the Year honors—we wouldn’t blame him for thinking he’s Master of the Street Machine Universe.
But we’ve known Denny and his dad Denny Sr. for a lot of years, and they’re the same regular guys they’ve always been. The boys are known for slick Pro Street-style rides; the roster includes three other shoebox Chevys, a ’33 Ford, and a ’62 Bel-Air bubbletop with a fuel-injected 409. The ’56 started out as a Pro Street ride too—this time for Denny Sr.—but his son convinced him to hand the car over for some major surgery.
The chassis was the first to fall under the scalpel. Denny cut out the body’s floor pan, then channeled it three inches over a home-fabbed jig. The frame was set up for Pro Street rubber, which meant it had to be redone to fit inside the body. The rear subframe was hacked off and replaced with a pair of rails from S&W Race Cars. To create a kickup in the rear, the rails were welded to the top of the remaining frame just before the rear tires. With the frame set up inside the body at actual ride height, the engine, transmission, and rear axle mounts were mocked up and pinion angles set correctly.
The ’56 gets its ground-scraping stance from a combination of S&W ladder bars, Fatman Fabrications A-arm front suspension, and AirRide Technologies Shockwave coil-overs on all four corners. Also sitting on those corners are Wilwood disc brakes and Colorado Custom Slotter Slater wheels (20 x 12 rear, 18 x 8 front) wrapped with BFGoodrich rubber.
With the chassis buttoned up, the Terziches turned their attention to the rest of the body. They fabbed a new floor pan, hung new rear quarter panels, and fitted the rest of the sheetmetal before hauling the shell over to Dave Mathews Auto Body for completion. Dave created a through-the-hood air cleaner and steel belly pans, modified the inner front fenders for extra tire clearance, and built an air vent into the passenger side fenderwell to duct air to the transmission cooler. When the bodywork was finished, Dave laid down the PPG Concept Orange and Chevy Truck White paint job.
Lest you think this shoebox is all face and no action, take a look under the hood. You’ll find 572 cubic inches of big block Chevy built by Evanuik Performance Engines. The 11.8:1 compression motor has a Merlin block filled with Crower and JE internals and a Comp Cams solid roller cam. The block is topped with a pair of prepped Trick Flow R-Series aluminum heads and a Brodix intake with a 1,145 cfm carburetor. Add an MSD ignition system and custom-built 2 1/8-inch primary headers, and you get an engine that makes 900 horsepower. Throw in a 300 shot of Nitrous Works giggle gas and you get—well, very, very scared.
We’re not sure why, but Denny has a thing for white interiors. The ’56 sports the glitziest one yet, complete with several cows’ worth of white and orange leather, Mini Me-sized roll bars on the front buckets to attach the RJS harnesses, a mondo audio/video system, and a custom dash insert. Everything is so nice, we felt guilty just looking at it.
Denny traditionally sells a completed car to finance the next project, but he’s not gonna do that with the ’56. “I usually don’t get the chance to enjoy my cars when they’re finished,” he said. “This one is special—I plan on enjoying it for awhile.” Can’t blame him a bit.
