Now I'm second guessing myself and can't actually remember if it has 2074 or 2180.

It doesn't matter, it's one of the two...there is not much difference in specs between them, and my buddy didn't use that engine anyway as the cylinders were rusted.

Dad's stroker engine sits on a shelf in his shop, maybe my friend will get to that later after the unit is redone and all. For now it has a clean, stock 1600dp.
