So in the two videos Blake has out concerning the optional Alternator option so you don't have to notch the e-body frame rail he lists two alternators. (2005-2006 Jeep Grand Cherokee / Commander SRT or 5.7L and 2006-2008 Jeep Grand Cherokee with 5,7L or 6.1L) are they both the same? anyone have a part number for the correct one??? thanks

So Update to anyone following... 6.4 392 / 46RH installed and no issues with the frame rail. Lot of clearance..
OK, for those following this thread. You can get it done by :
1, getting the above alternator
2. Finish drilling out the water pump casting where the top alternator bolt goes thru. Be careful, start small and step drill up to make sure it stays lined up,
3. Order a new pulley # 241277 - 6-Groove Pulley For Delco CS144 Series Alternators - 21mm Belt x 56mm, 17mm Bore,
from National Quick Start Sales, High output alternator, Alternator & Starter Parts .
4, When alternator arrives remove the pulley,
5. Get 1 metric cap bolt 10x150 100 long and 1 metric 10x150 40 long cap bolt,
6 . now the hard part.. When the mew pulley arrives you need a lathe or take to a machine shop and take 0.250 off the back (alt) side and 0.245 off the inside, see pics.
7. Reassemble and your good to go...
Hi Blake, thanks for the response. So i got the right Alt but it does not quite line up on the 6.4 392 crate motor. looks like i need about a 1/2 inch more forward so do you have or is there a pulley that comes forward a little more? any help appreciated.. see pic.
