what all work would i have to do to swap my 05 3.7 to a 5.7 hemi.

 

A lot of stuff, try the 3rd gen. forum for more details. It's really not worth it to try and you'd be better off just trading in towards a hemi ram.

 

not worth it at all.

the motor would cost ya more than the difference between the value of your truck and a a similar truck with the hemi. is yoru current truck stick? if so, then add a tranny to it...and whatever work/parts it would take to make it work with existing shifter setup. ecu won't be cheap, nor will the wiring harness if you need one. fuel lines/coils. new mounts. can our radiator cool the hemi?

in the end you're left with the same v6 looking truck, with a hemi in it, which isn't THAT fast...expecially cause throwing a hemi in it would cost more than throwing a 460 in it...this new hemi crap is over rated.

 

If any motor swap, go for a blown 427 Hemi, makes around 900 hp, I found it for like 40 grand.....

 

Why "swap" an engine that was designed for your truck anyway?

Why not be a real man and swap a built 4BTA Cummins in there? Big turbo, big injectors, major intercooling...250 HP and 450 FT-LB. Matte black 4" straight pipe behind the passenger side cab. NV4500 trans. Billowing clouds of half burnt diesel. Screaming compressor whine. And you could be the only guy with a 4 cylinder half ton in town. Hemi's are all good, but they are to Dodge what the 350 Chevy / 350 Turbo is unimaginative hotrodders.

exactly...the hemi isn't worth swapping. is the hemi 1500 fast? NO. is it fast in comparison to our v6? YES.

SO, after like $15,000, you'll have a truck that keeps up with most of the cars on the street.

 

Swap a 454 in there.

 

How about a bit of sacrilege? Swap in a twin turbo Japanese straight 6! That way when people want to race you, you can still say that it's just a 6 cylinder. The motors put out a TON of power.

lol...good call.

or put like 4 hayabusa engines in it...

 

Ha! How would that work? Anyways, I say to stick with doing it right, and just build your truck the right way. You can do whatever you can imagine with this platform. Save money, make friends, and still Have plenty of power! That way, you can enjoy it for what it really is. Yours.
