Ve 12 Valve Cummins turbo diesel with nv4500. Southbend clutch, ducky injectors, he351 turbo, hungry diesel injection pump. Second gen intercooler, fist gen rad, sound dreading.
Swapped last winter (2021-2022). 1986 3+3 crew cab c30. Gathered parts for about a year and took two months to complete. Waiting on parts with Covid was the worst part. Daily drivable and a blast of a rig to drive. 18+ mpg, swapped 4.10 rear end with 3.73 Dana 70, factory interior except pillar gauges with tach, boost, and egt. All functioning except AC. Done lots of little tweaks and upgrades but little has changed since initial swap. Built to be a reliable fuel efficient daily/ tow rig at a quarter of the cost of a newer rig.
