ahh i see...hey airram whats up its russ from colorado lol just got the ho cams and headers in and its reeall nice!! but ya as i was talking the mechanic who installed them..he said they make the procharger for 4.7 ltr dakota which is the same engine as ours and said he would do parts and labor for 5k. and lol he would be happy to do the pro charger on so he can see what it 'll do , he has single cab hemi and wants to race after wards! but that is a big investment. by the way , can you upgrade to a 5.7 ltr from a 4.7 with a manual tranny?

5000 bucks for a bare bones blower is a little steep... BUT thats including labor... so NO that's NOT a bad deal. Honestly the parts will cost up wards 4,000 bucks So although the price appears to be a bit on the high side... its not highway robbery.
As as far as doing a HEMI SWAP, yes it is possible but NO it will not be cheaper then adding a blower to the 4.7L. 8-10lbs of boost on a 4.7L will have most HIGHLY modded 5.7L's trying to catch up.

the 'ring land' at the top of the old 4.7 piston is very thin
and just a little detonation can destroy them
but perhaps with E85 fuel you can supercharge to low psi boost
if you add $600 more to the $5200
to purchase a J&L Electronics knocking sensing protection unit
for about the same $ you could probably transplant a 6.1 Hemi V8 in
from a SRT8 junkyard donor

Have you looked at Kennebells web site I have one on my mustang that is an easy install and its a roots blower so say good bye to that lag time of 3000+ rpm till you get the boost and you will gain even more torque if you ever tow.

Just to let you know I looked at Kenne Bell and they dont make a kit at this time but I know they are always looking for new kits to make so try calling them. When I got mine for my mustang i was only 2 weeks late on them making it off of someone elses car.
