So, ummmm, let’s see how many people I can make mad. I just had a Cummins ISX 15L engine land in my lap. Anybody have an M939a1 or first gen front engine mount frame cross-member, rear mounts, and doghouse (both for NHC-250)?
I’ll probably still go ahead with the ISL-400/13 speed since it is already done, together, and converted to 24v. I don’t think the Eaton/Fuller RTO-12513 trans would be up to 2,200ft-lb of torque, it is rated at half of that. But if I kept the truck unloaded and was nice to it.... I’d have to drive it to the GA ralley just to give everybody the business...
