I am still a newbie on these Cummins engines..Most of the 4BT's that I have come across were 105HP and they use the VE pump like the 6BT in the Grizzly.The 130HP uses the newer "P" pump and its intercooled..I have read pro's and con's on both pumps...
I geared the Diamond T to do 55mph at around 2400 RPM.Truck has a 4spd and I installed a mid 50's 3spd Brownie "A" box in it to help out..New powertrain has a 5spd.Once I get the tag number off the 5spd I will have a better idea of its gearing...
Truck originaly had a Hercules JXA engine in it (201 CI)
I am actually quite familiar with the flat head Dodge engine.My Dads daily driver well into the 80's was a 1939 Canadian Dodge (purchased in 1964).I also drove the car for years.We put a .040 over IND 265 flat head in it with a 1937 Chrysler 3spd with overdrive..Woke the car right up..I sold the car in 1991...It is in Chilliwack now
