The reason why the Cummins big cam is the best engine is because it’s a modern four stroke diesel that will do what any other Modern Diesel does these days except it does it without a computer and all the expensive worthless non needed BS.

Is the big cam 4 a good car?

The Big Cam 4 has the screwy low-flow cooling system, and while it does work, it doesn’t handle high hp very well. Haveing said that, I ran my 1st 1 million miles with the Big Cam 4’s and got over 1.3 M out of my fixed timed “315hp” that I later turned up to around 400…. Nothing wrong with them, but 400 hp is considered “low” by todays standard.
