I don't believe that Chrysler actually makes a "ready to go" complete drop in hemi for Wrangler. If your new jeep did not come from the factory with the hemi, shops that were modifying existing jeeps were fabricating and using other parts i:e, mounting brackets, wiring harness' modules etc. AEV produced the hemi kit to eliminate the need for scrounging up all the necessary adaptive parts. Also it's highly recommended to use the AEV ventilated hood because of the added heat from a larger engine and smaller engine compartment.

smaxberry So I did some more research on the NV5600. The gears are 5.63, 3.38, 2.04, 1.39, 1.00, 0.73. The current 6spd 4.46, 2.61, 1.72, 1.25, 1.00, 0.84.

I have been thinking how I wanted to spread out my build. 37s will barely work with the gear chart commonly found here. With the stock set up 37s would be about 2100 rpm. With the 392 and nv5600 37s at 70 and 4.10 would be about 2k. Now that doesn't sound much. Better, but the 6.4 at 2k is about 150hp and 360ft-lb, the 6.1 is about 135 and 310, respectively. Which tells me that the 392 at 2k would give me the same accelerations I see now at a little under 3k, but the ability to pass while staying in 6th.

I would like the ability to keep this as a DD, but wheel anywhere I want when ever I want. I am not that worried about being called a poser given the money I drop for the lack of dedicated off roading, plenty of CJs get bigger than needed engines winches and other goodies and never go off road.

Please back me up if you think I am wrong somewhere.

Jeep, Wrangler items in JeepsAreUs store on eBay!

They do specials on this engine at this price, I have never seen what their normal asking price is. But the 6500 is still what they are asking even though the deadline has passed.

AEV and Burnsville makes reference to the GetReg 238, hard to find, and hard to find good reviews. The other option for staying or going manual is the NV4500, ~2200-2400 trans. The NV5600 is the exact same trans. The first, second and final drives are the same, but the 4500 is a 5 speed and the 5600 is a 6. I have found the 5600 for under 3k, but have not looked into what else would be needed for mating to a 392. I would think just the bell housing.

The other option is going auto, unless you already are. The current auto will handle this motor. The predicted 8 speed coming next year, will not handle any Hemi conversion, and may not even handle the super charger option.

Jeffs Jeep Yard is good place to start if you are considering a 4BT conversion. I decided against this, even though I am looking at the same costs. Based on I lose cruise control, and there are not snorkel to work with it yet. Most of what I have done involves water, and the 4BT conversion leaves the intake even more exposed. Jeffs page will reference the same manual trans (NV4500) and offer a new 3 speed auto. The JK auto will not work. PM me if you need any more of my research.
good info for us! thanks

This is great research, Ive looked into some of this myself and I have the 2011 auto. and I really would love to keep the transmission if I can. I'll look into some of the stuff you mentioned and pm with any questions. Thanks again

Is the 6.4 significantly better than the 5.7?
Do the gains from the conversion even compare to a full hemi engine swap?
Would love some feedback from those of you with a hemi!!
