B-Model Engine Data

I can help a little with the Cummins numbers

NH= 4valve's per clynder NON turbo

NT= 4valves per clynder Turbo

NTC= 4valves/turbo/custom rated

Sorry I can't be of more help, but that's all I know.

I think I'm right on this the NH had the fuel lines on the outside and was a line and nozzle engine. And the NT hat the PT system and cam opened injectors

I have a NH-230 and a NH-250 with PT pump and cam operated injectors, and NTC-290 and NTC-400 with the same PT pump and injectors.

ALL CUMMINS ENGINES FROM THE 185 THRU 380 HAD CAM ACTUATED INJECTORS THE 185S AND 220S JUST HAD EXTERNAL FUEL LINES

Is anyone else having trouble reading this content?  oldmacksrus.com is no longer a viable website and I would like to see engine horsepower numbers to compare a b87 vs a b61
