Hot Rodding Inspiration For The Day; '73 Pontiac Tran Am
There must be something about dark green muscle cars and detectives: Bullitt, McQ, and even Spenser: For Hire. We don’t know what the common thread was, but all of those cars have strong followings among aficionados. For Kevin King of YearOne, it was John Wayne in a dramatic car chase in a ’73 Super Duty Trans Am that really stuck with him. That sounds cool enough, but this car was a little something different: Brewster Green, de-badged, only a small bird on the nose, Super Duty 455, and a four-speed.
Kevin is admittedly a huge F-body fan with a minor collection of notable cars brewing, and to him the perfect embodiment of a badass early second-gen TA was McQ’s ’73. Well, at least as far as looks go. Kevin had much bigger plans for the rest of the suspension and drivetrain.
The crew in YearOne’s Ghostworks Garage threw the DSE catalog at the suspension and chassis to make it a balanced handling machine, but it’s what’s lurking under the shaker that’s really eye-popping. A Chevrolet Performance Parts LS7 crate engine was force-fed a bunch of intercooled air by a pair of Turbonetics turbos to bring the power up to almost 800 at the wheels. That’s the daily driver friendly tune—it can do more.
McQ created quite a buzz at the 2011 SEMA show where it debuted, not just because of the color, but because all of the modifications were integrated so subtly that McQ strikes that perfect balance between restoration and custom. It’s impossible to not like this car.
Out at the MCOTY competition, McQ ran away from the pack in a hurry on the dragstrip, posting a best e.t. of 11.5 despite being severely traction limited. Set on kill with drag radials, it should be deep in the 10s. The story was the same with the speed/stop, where it posted a best of 9.179.
As for the real McQ Trans Am, one was obviously destroyed in filming, but we’ve heard that the second car used was later sold cheaply. Unfortunately, as the interweb rumor goes, it was destroyed while the owner was trying to evade the police. Kind of ironic, considering its past.
