Okay so just checked the specs on the different motors and well, DAMN.

360 hp @ 5,500 rpm - 5.0
365 hp @ 5,000 rpm - ECOB

295 hp ( 220kw ) @ 5200 rpm - 5.3

This is unacceptable, Chevy has to step there game up. The 5.3 is capable of producing a lot more power than what they are getting out of it. I have been a life long GM man and damn near a anti Ford guy but they are starting to loose me. Its a real shame Dodge cant figure out how to put a decent transmission in a truck.


Yeah it's sad when the Ram's 4.7 is putting out more hp than GMs 5.3. And, as I mentioned, the new hemi's have 390hp @ 5000ish rpm. Good thing GMs 6.2 is a badass motor. That's the one good thing about GM is that all of the V8s are LS block based...almost like the lego's of engines.

As far as the Ram transmission, they are working on it. Thought the 545rfe/65rfe currently offered isn't terrible...I put 90,000 miles on my old 2004 and currently have 32,000 on my 2011 - 0 issues. My dad also put 120,000 on his 2004 Durango and had 0 trans. issues. But, once you start adding power, or get the heat up, the 545 normally shits the bed thanks to the weak overdrive clutch packs. Ram is about to introduce the 8 speed into the trucks though, so hopefully that proves to be a good trans.

The thing that pisses me off is that the 5.3 is a great motor and if tuned right can easily hold its own if not top all other motors in its class.
