Well I was think about putting a 5.7 or a 5.9 into my dakota to replace my 4.7, since the price for performance parts for the 4.7 are incredible expensive and seem to not add up to much. as where the other engines have better figures and more options for performance parts after the facts. So would it be better to mod out my current engine or Drop in a new one? and what size?

 

find a 5.2 or 5.9. either swap or sell the 4.7 for a 5.2/.9

 

nope, id go for a 5.7 or 6.1 hemi . I think they are even supposed to bolt to your existing trans.

 

i do believe a 5.9 will bolt up to your tranny. Not sure about the 5.7 hemi tho!

but yea after seeing thunders dyno i was pretty much gaput on buying anymore performance parts for my dakota lol.

 

I think you have it vice versa and yes after seeing that pull I basically canceled every order I had.

 

I don't think the Magnum will bolt to the 4.7 trans. But, I could definately be wrong. Seems to me that if you could do that, every body and their 2nd cousin would be swaping the 4.7 6-sp into their R/T. I know I would.

 

thanks guys!.....lol jk. but yea, ive been depressed all day after that pull. even the guy working there was like "this dyno kicks everyones ***"

 

The 3.9, 5.2 and 5.9 magnums have a different bellhousing bolt pattern than the 3.7, 4.7, 5.7 magnums. The transmissions are not swappable.

 

What would be an easier Swap a 5.9L or 5.7L Hemi... I'm gonna put some money into rebuilding the engine before I would drop it in.

 

Hard to say. The 5.9 is going to involve another trans, a lot of totaly diferent wiring, new computers, etc... the plus to that is that these trucks came with a 5.2 and a 5.9 so the parts are out there. the 5.7 would probably work with your trans (PROBABLY) but you are still going to run into some final fitment issues as far as accessories, wiring, and computers. it's a freakin toss-up.
