I have an 02 1500 single cab 3.7 v6 5speed I was wondering if the 5.7 hemi fit in my truck????and where can I find all the parts I need

 

Your best bet would be to find a wrecked one with the hemi engine. You will need lots of small parts that will add up quickly if you just purchase the engine and tranny. With a wrecked one you will have all you need.

 

Yes, the truck is the same so the engine would fit just fine. But you will need the computer/transmission/wiring harness'/etc.

 

Engine/trans, full harness with computers for both, correct front springs, possibly different driveshaft, different radiator (for starters).

 

Engine mounts.

 

exhaust, radiator,radiator shoud,overflow tank, motor mounts, trans mount, trans lines, rad hoses, intake, not sure if fuel pumps put out the same PSI and flow rate. computers BOTH of them. Front springs unless you want to lower the ride height an inch or 2. drive shaft, Full wireing harness. and someone good at grafting the 2 together.. Probably a dozen things I have forgot..
