Macho Trans Am

The Macho Trans Am from DKM Design and Performance.

Here is a little of what I know about the DKM Macho Trans Am.

Dennis and Kyle Mecham back in 1977 wanted to improve the breed of Trans Am that were coming out of the Pontiac Factory. They turned out a limited number of Macho TA's in 1977 and were sold through their father's Pontiac dealership and moved very quickly out the door. Due to their tremendous success, they formed DKM Design and Performance, Inc. in 1978. They made 203 1978 Macho Trans Am and another 200+ in 1979 using the Pontiac 400 engine. In 1980, they stopped using the Pontiac 400 and used the Turbocharged 301 in 1980, which didn't sell all that well due to lack of performance and fuel constraints.
DKM also added a few comfort features as well like Recaro or Scheel seats, Fosgate radio, a lift-off or tilt-up hood made out of fiberglass (help shed 60lbs.) and also a custom paint job in a variety of non-factory colors.

Logos and Plaques

Each Macho Trans Am was numbered on the rear spoiler, front bumper and side fenders. The center bird on the steering wheel was replaced with a DKM logo and also a plaque was added to the center console to indicate that the car was modified by DKM Design.



Paint colors and Schemes

I am not really sure if there was any kind of paint colors and schemes. I have seen so many different combinations regarding this that I don't think I have even seen two that are alike. Sure, maybe the follow a certain pattern for the different colors and where they fall on the body lines, but as far as a certian upper color with only certain stripe and lower body colors I have not. Maybe they just did it custom for each person who ordered a car and didn't even have or follow a scheme.




For the 1978 Model year they used the W72 Pontiac 400, but modified the carbueration, ignition, and added Hooker Headers with dual catalytic converters and no mufflers for a net increase of about 50hp. You could also order a Rayjay Turbocharger which produced about 7p.s.i. of boost. In 1978, there only 8 Turbo Macho Trans Am's made and only 22 in 1979. You can tell the Turbo ones from the outside because the word "Turbo" replaced the Trans Am name on the rear spoiler. People have asked me before about a Turbocharged Pontiac 400 and I always told them that there never was one.... Well, I guess I was wrong. DKM also opened up the hood scoop to restore full breathing to the modified engine. They also modified the oil system by using what was called an "oil pressure restorer" by H-O Racing Specialties. It consisted of a canister with a one-quart oil capacity mounted on the firewall and pressurized. If oil sloshed away from the dry-sump oil pick-up in the oil pan, a valve opened up and oil surged into the engine to fill any gaps in oil pressure. The Macho Trans Am could receive 4-speed Borg-Warner, an optional 5-speed Doug Nash transmission, or the automatic transmissions were reprogrammed for quicker shifts. Also, the dash got a 160 MPH speedo and a 8000+ RPM tach. The suspension was also modified by a set of Koni shocks set at their softest rate, front springs tempered for rake and recalibrated for geometry. They also included the wider wheels and heavier sway bar much like the WS6 Performance package.



How did it perform?

Each one performed differently depending on what options you ordered.

If you want to do a little research you will find road tests and track tests of the Macho Trans Am's in Hot Rod magazine July 1978, Motor Trend magazine June 1978, and Autoweek magazine February 3rd 1978. Hopefully this will answer some questions on what exactly a "Macho" Trans Am was and what kind of performance it had.


Mecham Design, Performance

Yes, they are still around to this day.

Mecham Performance is still located in Glendale, Arizona. They still do performance, they still do parts, they still do business. You can check out thier website here:
