Manifold is N14. Turbo also looks to be from N14. HT3B did not have marmon flange compressor outlet. Don't remember model number, it is a divided entry. The turbo/manifold combo above will make things work sooner, small port manifold and turbo, however, the exh ports on N14 were small to...

Old stuff ran hardest at higher rpm. That is why the stinger came about on the PT pump. The plug in the gov hsg is removed and a rod welded/brazed to the end of the plug. Defeats the governor and you have almost unlimited RPM. As RPM comes up, so does the fuel pressure. Yes, the torque was a bit...

That is because an engine turning at a lower RPM burns less fuel, back then, they knew that but hadn't figured out how to move the torque curve to 12-1600 rpm, they made the best at 2000 +. Also, back then you couldn't have used the "gear fast, run slow" concept of today because there was no...

Might. And there are plenty on threads on it. With pictures. @162tcat, I just saw this thread. That would I believe, be a PTR style fuel punp. The ones with the ball in the shaft are PTG. PTR were used early on, and had external aneroid on turbo applications. PTG was later and incorporated the...

Dunno, there were 100's of thousands of mechanical C's made, still making them for non lead emissions areas of the world. One would need to find a book for the C8.3M version. If you install the head from an M version on an on road of construction type of engine, you will have smoke and power...

Heads, cooling system, fuel system and exhaust. 400 hp rated C series are mainly found in rec vehicles. They were pushing 500 out of the mechanical C for marine in recreational apps. Automotive was rated at 325 max for trucking. Hey Bandit, can you tell me why Cummins went from that small, like...
