Max Torque Big Block

One thing to keep in mind with a Cummins swap is weight. They’re 1100 lbs and IMO the pre 90 dodge truck platform is not properly set up to handle that weight. I had an 89 CTD that tore the LCA Mount right through the rivets. I had noticed cracking around the rivets but didn’t think enough to do anything about it. My friend with an 89 CTD had the same cracks at the LCA mounts. My fix was to buy an entire front chassis from a 91. They redesigned the front cross member and LCA mounts to be a single stamped piece.

Just a thought. 6BT is an awesome engine, but it’s also a heavy pig.
