Looked at your thread. Really nice work. You have excellent fabrication skills...and stamina. That is so much work!
When I was young I found ways to have a life AND do engine swaps. At 68 I no longer have the energy for such a project and would seek another avenue. Even though I find the Ford cab more desirable, Dodge has offered Cummins for a good long while and I've had good service from Dodge; better from Ford; not so much from GM.
