Just got this '68 together for a friend. It was his dad's car, sat for years.
We built a 383 stroker for it, original 327 was long gone. Dyno'd it at 390HP to the wheels, Lots of go-fast stuff, original 4-speed, all new suspension bushings and brakes.
Got a new hood coming as well.
Really fun to drive. It handles like a truck, but its loud and fast.
