This new Jeep Trackhawk Dodge came out with is insane...go take a look. Let's put a Hellcat engine in a Grand Cherokee!! 707 HP grocery getter. Get her one & she won't complain about anything but the price. I reckon $10k AMD over sticker minimum if you are lucky.

It's a dog on the acceleration but solid on reliability.

To clarify, I will gladly give up ANY fuel mileage gained by AFM to not have AFM. Guess I'm old-fashioned, but it's just another system to screw up. And GM hasn't done much convincing that it is a bulletproof system...

You are correct. The 6.0 motors in the 2500 are not aluminum motors and do not have AFM. They are rock solid and I hope they never screw with those.

No question that GM shot their self in the foot with AFM and VVT. Failure is not a question of IF but WHEN. The 5.3 and 6.0 Gen III vortec pre AFM are the best engines ever built by GM, best fuel economy and best reliability. If only they had married it with an 8 or 10 speed tranny. As for the AFM, it don't work so good. I have never heard of an AFM engine getting better fuel economy than a non AFM Vortec and the ones that have disabled it started to get better mileage by 1 or 2 mpg.Last edited by muzzlebrake; 09-08-2017, 07:03 AM.

That sounds awful high unless they kept driving it when a lifter failed and chewed up the camshaft?
