He said he wants 350 HP. If he doesn't have 1500 bucks to drop he better find another hobby. The XE268 is a step down from the Crane part number. If you saw the timing events, you'd understand.
Not seeing it... crane has more EXHAUST (234 vs 230) timing and lift, but a little less on the intake. Alright, I don't have the .200" numbers but I can't see there being a vast difference on a hydraulic at this level.
