I can get the HEMI engine stuffed into my dakota and get everything else such as new computer, trani, rearend, etc for est. 5,000. NOW...the question is..is it worth it?

$5,000 total, or $5,000 labor plus parts?

Last I saw the crate Hemi was running around $6k by itself. A 46RE or 48RE transmission would cost about $1,500. Add custom fabrication (the Dakota engine bay is a smidgen too narrow as-is for a Hemi), labor, etc...

The head-turning aspect would make it a worthwhile project if you have the cash and hookups to make it happen, but it will cost quite a bit of money, almost as much if not more than it would cost to trade off your V6 to a SY R/T (swap your rims/hood/etc) and then add a supercharger or nitrous or ???

If they would be willing to put that quote in writing, stick to it, and you could afford it, I say go for it. You'll gain a lot more out of a Hemi swap than you ever could trying to add bolt-ons or a power adder to a V6, and the gawk value alone is worth twice what you'd pay.

The 5.9L engine rates at 250hp/345tq at the crank
The 5.7L Hemi rates at 345hp/375tq at the crank

Quite a bit of difference stock to stock... However, the Hemi engine has a drive-by-wire throttle body which makes some modifications nearly impossible vs. the more simplistic 5.9L engine. There are still a number of mods for the Hemi - air intake, supercharger, headers (probably would never fit in the Dakota), exhaust, etc. and I'm sure as the platform progresses you'll see more and more performance goodies.

I knew it would be quite a differance. They told me if I decided to do it, My truck would have a hard time sitting still. Meaning what Im not sure? But I know If i did it the 20's would go and I would go back to 16's or 17's. I dont think 20's would be a bright idea with that kind of power.

There's all sorts of people running 11's-13's with 20"s on their truck (they usually swap to slicks at the track though). Scott Q Dyno'd at over 600rwhp and he uses 20" Intro Vikings.

Just because nobody\'s done it before I'd have to say you'd probably end up somewhere in the 13's... 345hp * 20% driveline loss = ~276rwhp... Lots of guys in that range with the 5.9L engine and some heavier bolt-ons.

what exactly do you mean 20% driveline loss?
The horsepower that is quoted by manufacturers is at the crank, measured while the engine was probably sitting on a stand. When the engine is installed in the truck, there are items that siphon off some of that horsepower before it makes it to the rear wheels... Power steering pump, water pump, mechanical fan, A/C condenser, torque converter, transmission, gears, etc... All that resistance lowers the amount of power that makes it to the wheels, hence the rwhp (rear wheel horsepower) figure. On average, a vehicle with the full amount of accessories (P/S, A/C, etc) plus an automatic transmission loses about 18-20% of its power, manual transmissions 14-18% or so.

Only a dyno run will give an accurate representation of what you're actually putting down to the ground.

I think having a Hemi Gen III Dakota will be quite nice and will draw a helluvalot of attention.

I bet that Dang Ol hemi would fit nicely into my Old Ass Gen 2 Dakota without a question (It's bound to be narrower than a 440! which fits in just fine) But I am going to stroke my 318 and build the sh!t outa it long before I spend $6000 for a crate motor! The Local 4x4 shop is in the middle of a Hemi swap in a Wrangler... "Bolt in Kit" my ass! You should see all the things they have been making. Quite quite amazing! :biggthump

Wanna do somthing cool, get a Cumming in their! Banks did it, Y can't I? Easy, my hood isn't long enough! Damnit! It's still tempting... a 98.5+ 24 Valver with a 12 Valve Injection pump (It's so easy to tweak!) and dual 5" Stacks in the bed... Oh god yes! That's be badass! K back to reality... :eek:wned:
