A couple questions about my CSX4000

Don't hook up the oil cooler unless you track the car. With the size of the radiator the engine is already over cooled. If you do hook it up put in a thermostat bypass

Any reason you're rebuilding the engine instead of just getting a new one? You have no idea what can of worms is in there. It sounds like the car was rode hard and put up wet and a rebuild that will discover and repair all the abuse it's seen will be as much as a new short block. And you won't be revisiting it again in two years
