My dad bought this car in 2013 as a nice driver that was mostly stock. Later we found it had been in a wreck at some point in its life and the subframe was bent. That led to a Heidt's Pro G subframe and 4-link rear suspension upgrade with coilovers all around. The motor is a 400ci pontiac from a '69 firebird, bored out to a 409. Transmission is a 200r4. We've also added electric fans, vintage air, Recaro seats, a 10" sub and amp, and have more upgrades planned for the future.
