DB2 350 Wheel Horsepower Build - Banghart Diesel

Edited

Overview

4/9/2025

Banghart Diesel Performance contacted us early in 2025 about a customer's build they had planned. It started off as a plan to refresh the original 1993 engine, but quickly evolved into a total engine replacement after teardown and inspection.

This particular truck is a 1993 Crew Cab Long Bed Dually that the customer wanted to restore and keep in the family as a fun driver. This gave us the flexibility to have some fun!
