So your telling me I can get 50 more horse just turning up the fuel? For the price of injectors turbo etc you could buy a used 400-444 big cam I bet.įormula 350s are a big cam and they max out at 1800rpm vs 2100 of a regal at small or big cam motor They went to a big cam for a few reasons. That's a pretty hot small cam from the factory. What is the difference between a small cam 350 and a formula 350.

Mine doesn't run hot exhaust temp, just runs good. I have same engine, put a 400 charger on it and next size up injectors and alittle more pump pressure and it will get you there. What do you change to generate more ponies.I'm guessing injectors, reset injection pump,bigger turbo, timing?ģ50hp is not enough in today's world.get run over on the road!

Future developments (Big Cam III in 1982 and New Engine in 1984) are indicated a 10% mpg gain is targeted for the 1984 engine over the equivalent Big Cam II model. A 15% fuel economy improvement was realized in the 1975-1980 time frame. The NT-855 is traced from its pre-1975 version with a rated speed of 2100 rpm (Small Cam), through the 1975 introduction of the Formula rating in which rated speed was reduced (1900 rpm) while maintaining rated power output, to the 1976 Big Cam-Formula (1900 rpm) and 1979 Big Cam II-Formula (1800 rpm) versions.

Examples of its application are commercial heavy-duty trucks (bulk of the market), large articulated farm tractors, commercial fishing boats, and generator sets (standby or continuous duty). The current model, the Big Cam II, is a turbocharged, four-stroke, in-line, six-cylinder engine with 855 cu. Improvements since 1957 in the Cummins NT-855 heavy-duty diesel engine are described.
