Really that depends on what ur trying to accomplish with your truck. If ur looking for gas saver go with another 5.2 or go with the hemi 5.7 with MDS. Looking to go fast go SRT... Im gonna also be brave and pls no one shoot me but have u considered a non dodge motor? Like a chevy 454 carburated or what alot of people are doing right now is an LSX motor from chevy Which for a motor swap is my favorite. Just giving u options...Again dont kill me cause i mentioned chevy lol.

The availability of "plug and play" computer controlled engine systems makes any swap a bit easier to do. However, starting with a vehicle that already has these systems becomes a bit problematic when you want to start swapping and have incompatible systems. At that point, you need the services of a highly qualified integrator/programmer to make it all work.

However, doing a 5.7L or SRT-10 swap into an older Dodge is made a lot easier if you get not only the engine but all the control systems as well.

Yeah, you'll have some things to figure out but not near as many as if you were to drop a Bowtie into a Ram (boo!!!!) that already has engine management systems in place.

I don't know about that bulletproof thing. I've grenaded 3 SBC's but then again, they were race engines that were abused pretty hard.

My recommendation would be to go w/ a carb or one of the new self learning FAST EFI setups. Carb would be what I'd do though.

Check out Hot Rod's online archives for a Junkyard Jewel article they did on a 5.9L. Edelbrock heads, Comp Cams roller, singple plane intake, 1.75" headers. Motor made 440hp w/ a well used bottom end. The 5.9L should be a bolt-in replacement.

My nod goes towards the 360 as well. Especially if you go with the Crate Magnum 380 or a 408 stroker.

oh yeah...a 408 stroker would be cool. With it being based on the Magnum line of engines, other than a custom program from B&G or someone similar, you could use all the stock sensors.

Forgot the custom tune. A nice Holley 750 (or for better street manners an Edelbrock 750 or one of the new AVS series). You'll be able to tune it w/ one screwdriver and a wrench.
