Details

1979 Mecham DKM Macho Turbo Trans Am # 11. This Trans Am Resto-Mod has undergone a frame-off, nut-and-bolt restoration that was recently completed. This is a fully loaded, black-on-black T-top car both from the GM factory and Mecham Performance. It is certified by Dennis Mecham and the dash is personally signed by Dennis Mecham. It comes with documentation including the original GM Build Sheet and the original Mecham dealer invoice showing that it sold for $18,082.27 in 1979. It also includes DKM in-house Build Sheets showing the installed options including the turbo system. The interior features DKM-installed black simulated leather Scheel heated race seats. The iconic swirled dash bezel was professionally restored along with the resto of the dash, gauges, lenses and clock. A chrome Hooker roll bar, which was an option from DKM, was added along with new carpet, headliner, center console and door panels with all-new door rubber and T-top rubber. It also has all-new glass. It’s powered by its matching-numbers L87 400ci engine mated to a non-matching-numbers 4-speed manual transmission connected to a 3.42-ratio 8-1/2” posi-traction rear end, with factory 4-wheel disc brakes providing the stopping power. The engine was completely rebuilt with the block bored .030 over, new H-Beam rods and custom forged pistons. The mains were line honed and the top was decked square. Stock heads were rebuilt with new press-in bronze guides and outfitted with all COMP Cams springs, valves, keepers and retainers. A special grind COMP Cam was matched for the high-output racing Turbo Force system. It’s equipped with a Holley Sniper fuel injection unit on a single-plane manifold, and high-output manifolds feed the Rajay turbo via a 3' exhaust custom Pypes Street Pro exhaust. Additionally, the engine is outfitted with a CFV serpentine system with Sanden-style R134 air conditioning system, aluminum radiator and dual puller fans. During restoration, the body was soda-blasted, the frame was blasted and powder-coated. It rides on refurbished 8” snowflake wheels with KONI shocks in the front and rear, just as it left Mechan Performance. The interior features a custom Bluetooth stereo with a custom trunk enclosure housing a Fosgate 10' subwoofer, 6x9” speakers and Fosgate P800 amplifier. The trunk also houses the Optima battery.
