Back when my son (Dizuster here) was in High School.he traded cutting lawns for a Duster. 318 short block, 360 heads and intake, TQ, The only "hot rod" parts were a .484 purple shaft , headers, 2 1/2 exhaust. Wire wheeled and drill lapped the valves. He and buddy swapped it into a 71 Dart . The stock 727 converter and cam kept it from spinning the G60×14s. 4.10 gear corked up. Him and buddy made a million passes in it. Ran 14.0@100 .
Put a lot of bigger motor stuff to shame. Heck it was faster than my bone stock 383 Dart GTS 4 speed convertible (3.23 open, 14.7@95)
