What RPM's do the 4bt's like running at? 2100 constant? How high can you go for a long period of time? Thanks for your time, Jed
Jed;I'm working on my '47 WDX Power Wagon with 5.83's and the only gear swap is to 4.89's. I'm definently putting in an overdrive tranny maybe taller tires later. 35" are on it now. It's not a daily driver so the overdrive tranny might be enough for what I do with it. It would be real nice to go 50 or 55 in this thing once in a while without the engine screaming. I restored it ten years ago and I don't think I've ever gone faster than 40.
