1979 I purchased the 1/4 ton truck from a coworker and have modified it ever since. He replaced the original 4 cyl motor with a 265ci SBC. I replaced the 265 with a 283 then, a 327 and then, with a 350 and now with a 383 Stocker… here’s the kicker. Nothing was wrong with any of the motors… too much time on my hands.
