Some street-rod trends seem to shy away from performance — or least the illusion of performance — while focusing more on sleek exterior design, flamboyant interiors and engineered suspensions. Ed Umland of Eddie’s Chop Shop still showcases engine firepower and makes sure the car isn’t overwhelmed by paint and billet.

This twin-turbo ’34 coupe currently under construction at his in Orangevale, California, facility boasts a nasty twin-turbo 598ci big-block that proudly flaunts all the required tubes and plumbing to such a menacing degree that there’s certainly no reason to apologize. It’s clean and organized, yet radiates raw horsepower on all visual and sonic levels.

First, the details. The long-block was built by Don Zemina of Motor Machine Super Shop and is based on a Dart tall-deck block fitted with Callies crank and rods, JE pistons, Crane cam, Isky lifters, Smith Brothers pushrods, Federal Mogul bearings and ARP hardware. The Dart Big Chief heads received a little massage work before the Manley valves and Jesel rockers were installed. Wrapping up the long-block assembly are a Melling oil pump, Milodon oil pan, Jesel belt drive, MSD distributor and Titan head gaskets.
