I've read your buildup, and you did a nice job. I think you came out ahead with the 6bt over the 4bt. I wouldn't hesitate to copy your setup. Actually, it would work nicely in my M152...retiredguy wrote:Just reading through you blog and being you are thinking of Cummins caught my eye. I have a custom M37 running a 93 6BT and I was reading a concern about power and mileage. I understand that the 4BT is under powered for my liking so I went 6BT. The 6BT went realitively well and would cruise at 65-70 mph but it performed more like a tractor, you know more throttle more RPM. My son who specializes in Cummins said Dad, you have a VE pump so put in a fuel pin. It's cheap and easy to put in. Now it runs more like the electronic Cumminis and somewhat like a gasser. And I still get 22 mpg. I know I'd get better if I had 4.10's or smaller tires. I've got Michelin XML 39" on it. All in all Look into the fuel pin. There is also a governer spring to swap out but I have not tried that yet.
