Please do not make statements like that based solely on assumptions or opinions alone (or perhaps re-regurgitated crap off social medai sites). here are the actual differences ...


x15 mid-tier (X15 CM2350 X114B – Efficiency Series. 450hp engine was referenced)...

----overhead cam: 3690406
----pistons: 3691387
----connecting Rods: 3689108
----Block: BB1958-assy (casting 4311621)
----crank: 3691444-assy (3691443 crank w/o tone rings, etc.)
----head: PP10489 (4101454 exhaust valves, 3685996 intake valves )
----injectors: PP10425

x15 big tier (X15 CM2350 X116B - Productivity Series. 605hp engine was referenced) ...
----overhead cam: 3690406
----pistons: 3691713
----connecting Rods: 3689108
----Block: BB1950-assy (casting 5440753)
----crank: 3691444-assy (3691443 crank w/o tone rings, etc.)

----injectors: PP10425

x15 big-tier (X15 CM2350 X116B - Performance Series. 565hp).
----overhead cam: 3690406
----pistons: 3691713
----connecting Rods: 3689108
----Block: BB1950-assy. (casting 5440753)
----crank: 5440758-assy (5440757 crank w/o tone rings, etc.).
----head: PP10490 (3686661 exhaust valves, 3685996 intake valves )
----injectors: PP10425


What is actually same ...
----Overhead cam =- same
----Connecting rods =- same
----block =- same between the Efficiency and Productivity series.
----crank =- same between the Efficiency and Productivity series.
----injectors =- same
----Intake valves on head =- same


What is actually different ...
----head =- different (due to different exhaust valves only)

----pistons =- Performance AND Productivity series has the different (due to slightly different compression ratio) than the efficiency series.

----block =- Performance series has Slightly shorter and heavier than the one used on the Productivity/efficency series engines.

----crank =- Performance series has Slightly shorter and heavier than the one used on the Productivity/efficency series engines.
