It's in a '78 3/4 ton 2wd Chevy. The truck is worth nothing really, it been picked apart. But the motor, according to the numbers is a '69 Impala 427, which came factory with a cast crank, cast domed pistons, 10.25:1, 335hp at 4800RPM; 460ft/lb torque at 3200RPM. All thats really worth anything on the truck is the TH400 and the 14 bolt rear. It has been sitting for 5-6 years, so seals may be dried out. Supposedly, the guy thinks his dad, who passed away, had rebuilt it and said it has a lumpy cam in it and that they would always easily burnout in the truck. So, is a '69 427 motor worth this much?
