BB motor Question

If you do indeed decide to go with the 400, really check into the measurements for whatever cubes you choose to build. Some combos with long rods leave very little comp height on the pistons. For a bracket build, I personally would avoid combos that use a 1.12/1.15 range pin height. I'd prefer a longer compression height piston along with a mid range ring package that can get you some longevity out of the build. Nothing like getting 3,4,500 runs out of a engine with nothing more then, oil, plugs, and maybe a valve spring swap. :D
