The construction deadline was the Goodguys 15th PPG Nationals in Columbus, Ohio, this past July, and it was finished with no time to spare. The 18-month build time was miraculous in light of the sheer volume of fabrication, but the throngs of curious visitors at the Woody’s Hot Rodz booth told the story, as did the big smile on Mike Coughlin’s face. The real shakedown, however, would come at the inaugural Popular Hot Rodding Muscle Car of the Year (MCOTY) competition, which was covered in the Dec. ’12 issue of PHR. Since then, the Jega has become acclimated to the rigors of the road, and now resides with Mike Coughlin, who loves sharing rides in it with his sons Clay and Jack.

As for the Morrison Max G chassis, the Vega version has gone into regular production, and a couple more have been sold for Vegas, as well as a slightly longer wheelbase version for the '75-80-era Chevy Monza, Buick Skyhawk, Olds Starfire, and Pontiac Sunbird. Apparently, the GM H-body is beginning to see a resurgence as hot rodders are awakening to the idea of superlight, ultra-short wheelbase street machines that can handle. It's a trend we'd like to see revisited with other platforms too. We can only imagine what a similar '70s Ford Pinto, Mustang II, Dodge Colt, Pontiac Sunfire, or Olds Starfire would be like with the right chassis and powertrain!

By The Numbers

“The Morrison Max G chassis would easily handle the punishment of both road and powertrain, but first it had to be mated to the body.”
