well if it was stock 58 , then the 348 tripower @ 280hp , with a std tranny and posi they moved pretty good. The police 348 had 315 horse. By 61 it cranked out 350 horse and then gave birth to the legendary 409 and the 348 was gone from under a car hood. The Biscayne up top looked like it did well on the track. Nice pic.
