Now you could build the 5.7 and make it into a monster but then again it would take a boat load of money to make it all happen. If you kept the 360 and spent just the money that you would spend for the hemi alone you would end up with something that would churn out 450 to 500 HP.
Respectfully...I don't agree!
If you buy all new components and have someone else do the work, then it will cost $10000, but so will a 408 stroker.
On a budget, you can do this.
$1500 Used 2003-05 Hemi Engine and trans (20k miles)
$350 cheap MIG welder
$150 Motor mounts and Metal stock
$350 PCM reprogramming
$000 Adapting factory harness to fit Gen II Dakota. ($995 pre-made)
$75 Driveshaft work
$250 Custom Y-pipe
$300 Adjustable pressure fuel system.
$150 6.1 Cam
What you would have would be a 400hp HEMI with a butt-load of torque. If you take my Buddy's Ram, he runs 13.68 with a 4800lb 2005 Ram with this engine, the cam, shift kit, and headers. In a light Gen II Dakota, we are talking at least 12.50's here. Also, remember that the new Hemi is about 120 lbs lighter than the 318/360.
Spend and extra $3000 and you can have a FAST XFI system, higher stall converter, Headers, a 273 Cam, and you will be pushing 500hp! For about $6000! Lets see anyone build a 500HP 408 for that price. All it takes is some fab work and a few long nights, but if you have the skills, then you can do it. I am working on it right now, so are a bunch of other Dakota guys.
