The Macho T/A, which was the brainchild of Pontiac dealers Dennis and Kyle Mecham (hence the DKM name), was a mildly tuned and slightly refined take on the Pontiac Firebird Trans-Am. The brothers rejetted the 400 cu. in. V8’s carbs, added a set of Hooker headers, installed a real full dual exhaust and installed a functional hood scoop. Heavy duty Koni shocks, new front springs and some small visual upgrades rounded out the package, which sold for around $3,200 in the 1970s.
This Macho T/A, which is just no. 135 of 204 produced in 1978, has spent its entire life in Arizona and retains many of the original Mecham-installed parts, including the Hooker exhaust. The previous owner also slapped a bunch of modern-day upgrades on the 400 V8 engine, including new pistons, new heads, a Comp Cams camshaft, a QuickFuel carb and Edelbrock Performer aluminum intake manifold, among much more. The old four-speed manual transmission has also been tossed out in favor of a modern TKO-500 five-speed.
Other modern upgrades applied to this car include 18-inch BRE/Year/One wheels designed to look like the Trans Am WS6’s original snowflake wheels, which are wrapped in BFGoodrich G-force Sport Comp 2 tires, and QA1 coilovers. The car came decently equipped from the factory as well with air conditioning, power windows and a hurst shifter.
