The hp rating on the "new" 4.3 is 260 so yes i did make a mistake on the hp i thaught the Ford base engine was the eco boost at 360hp. the new 5.3 is 330 with DI and DOD or whatever you want to call it, I still by my post it's a joke. And if you think about it that's all they can do the mighty Corvette LT1 is 450 and it's a 6.2 so there is no way they will have more hp than that.

From GM's media website, "All engines feature an engine-driven mechanical vacuum pump to enhance braking performance"
I imagine this is the mystery pump.
Since they are moving to electric type power steering that removes the need for a PS pump to provide for the hydraboost braking used on some models.
