yeah man but definently if you find that please do post it so I can show em, i appriciate it man
what sucks is just messin around online there's a TON more parts for the 5.9 an he wants to build this engine up pretty good, but i'll let me know an look into what he can do to his 4.7
What about the 3.9L V6 ??? is there any hope for my dakota
the 5.9 out of the fullsize is the same dealio , grab one of those and get some new motor mounts and then get a mopar performance PCM because they work nicely with the 5.9. You are going to have to do some serious work beefing up this motor to make it high hp ready, just remember they like to ping alot, they have shitty intake plenum gaskets that blow out all the time so check those, they have issues with the IAT, EGR, plug wires and TPS.

i dont know much about the engine but i found a car and driver (ish) site that said that the 5.7 sucked and you could easily build up the 4.7 to be way better, they said all they could produce was a small chirp out of the tires,and it was in no way as smooth as the 4.7, if i find the site ill post it. I think the hosepower diffence is like 235 to 250, so for gas mileage, i think it would be a waste to swap to bigger engine.
I dont think you know what motors your talking about. The 5.9, 5.2, 3.9 are all based on the same block, the 4.7 is completely differen, and the 5.7 is the new hemi.
