Bought this in '88 when I was a junior in high school, and it was my daily driver until halfway through senior year when I decided to do some rust repair. That turned into new GM quarters, fenders, header panel, and door skins, repro tail panel, rockers, floor pans, , and hood. Was a 327/210 PG originally, now is a 406 w/ 700R4 and 4.11 gear.
A buddy and I drove it from Omaha to Austin, TX and back about 10 years ago...it did pretty well, pulling down around 15 mpg with a 4779 Holley.
