RmJr, Welcome to the site. Lots of knowledge here.
I don't currently have a running big bolt, but for years I had a 46 2-ton. It was a stock truck with 8.25 rear tires. Single speed rear end. It ran the original 235 splash lubricated babbit rod bearings. I freshened up the engine, but all stock. I was even running points ignition and the original radiator. The only non original things were a 12 volt electrical system and disc front brakes. The truck now resides in Arizona and I'm sure the owner would give you a ride if you are close to him.
I was able to run on the highway comfortably at 55. I would occasionally see 60 and at one time I looked down and I was doing 68. It most liked the 50-55 range. Loaded was another story. The most I had on the back at one time was 12,000. It went, but not very fast.
Get it running on all the stock stuff. Make sure the brakes work well. Then go drive it and judge for yourself if it will work the way it is. I suspect it will as any modifications to make it go faster will likely become very expensive by the time you are done.
Good luck and keep us posted on your progress.
