    HPDI crankcase ID

    Can anyone tell me how I can figure out visually if a HPDI block is a 225 or 250?

    Pretty sure they're the same. ECU programming is the only difference.

    They are not the same block.

    Look for a casting mark somewhere on the block.

    60X on a 250 block. 60Y on a 225 block.
