My first engine swap was in '72 stuffing a 440 out of a big Chrysler into my 4dr '64 Belvadere. 2.72 rear screws on bias ply rags I'd run that thing past 120 in a heartbeat ! It took a while to get there, compared with the usual street racer of the day, but I swear it'd do 140 !! At least it buried the speedo and kept on pulling ! The crazy things we did as kids :shock: :shock: :shock: :shock: :shock:
