OBS injectors flow less cc's than SD.
SD injectors are split shot, OBS are single (as long as they're not california emissions).
SD IDM has higher voltage than OBS (can get more power out of injectors this way)
SD has bigger turbo (flows same amount of air but gets it to engine much faster in the torque band)
OBS has forged rods; much stronger internally.

The Super Duty can be upgraded easier for more power. But that doesn't mean the OBS is weak.

What exactly are you trying to do?
New truck? New engine for your truck?

I love my obs PSD. Sure, not as much power as the sd's, but that'll change before long.

im wanting a bigger cab pretty much. and im not looking to spend alot. my truck is getting tired. i kinda want to keep the same body, since i just have so many spare parts for it. plus junk yards are full of them. f150-f350s

Oh I see. Was just wandering.

I like the obs look over the SD stuff any day.
