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.

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
