I say 06-07 5.9L just cause you can put EFI-Live on it.

No EFILive for the earlier CR's or the 6.7s

if you want something for simplicity...

12v p7100 would be the easiest swap.

Hmmm, thanks so much for your thoughts! This will be a daily driver, but the engine has 180,000 miles on it and is slowly dying. And, with my 37" tires, I need more torque. I can't even spin the tires at speed in the mud anymore. So, I can drop a 360 into it, turbocharge it, or stroke it. Either way, I look at between 30 - 50% more torque and a huge hit on fuel mileage. The most I can coax out of my 5.2 with a manual transmission is 16 - 17 MPG's. On the frames, I thought the frames were all the same, did I miss something?

The frames are mostly the same. Likely some different crossmembers, but other than that.



What gears do you have? If you go V8, get some better gears, if going diesel, you're going to need D60/D80 combo with 3.55 gears.

The frames are definitely thicker steel, and I believe are 2 inches taller under the cab, but that may wrong.

I've heard a couple guys swap in a Cummins into a 1500 frame. I'd be leery myself if you start pumping it up and towing bigger loads with it.

With the 1500 chassis the hot ticket would be a nicely put together 5.9l gasser with an ATI Procharger bolted onto it, nicely tuned. Dana 60's would be good, too, since the corporate diffs would scream and cry.

Thanks for the thoughts on the trailer. Agreed dem prices is qwazeee.

Thank you for your service. Going to put a further note about his on your motor thread to not derail any further on the topic.

OP -- Stroke a 360 and drop in. Get a separate diesel truck.

Yep with some super cool my **** don't stink prices too.

If you go with the 5.9 Diesel you won't be taking a hit on fuel mileage, you'll be gaining fuel mileage. the 5.9 diesels you'll see 18-22 mpg, maybe a hair better...especially with the good ol 12 valve. the 6.7's you'll be lucky to see 16-17 with all the emission bs on them.

they 6.7 does well on economy if you delete the emissions junk.

my 5.9 does 14-15mpg average

but it is at 550-650hp range...
