My Pond block is tilted up 1 degree in my ERA, with the higher end toward the water pump. I didn't set it this way purposefully, I followed the instructions by setting the transmission tailshaft above the chassis. This is supposed to give enough angle on both ends of the driveshaft so that the u joints work properly.

The expansion tank on my car is at 2 degrees, so it is 1 degree different from the engine. I don't think the angle of the expansion tank is critical.
