I have a 4400 chevy that I am going to build into a diesel hauler or maybe even a wrecker if I can get it reliable enough. I have already bought a IFS motorhome frame with 19.5 tires and I believe a 4.11 ratio rear. My question is I have a 4bt, a 6bt, and I finally found a 453T. I really like Griggs truck and honestly that is what I have planned but I have these cummins motors sitting in my shop. I want to see what you would use in this truck if you had these choices. I have an allison trans for it and I am looking for a roadranger in case I go the detroit route. I am talking about actual fit in the truck and what modification/fabrication would be required. Any thoughts would be greatly appreciated.
Thanks
Brad
