To me the carb is a compromise for they 3g hemi. Fuel was meant to be sprayed through an injector bung on this motor, and thats where it should stay.
I don't want to go againsts the guys at Mopar who established technology and spent millions of dollars building this platform only to handicap it with a carb.
On that note, STEFF will be stoopid fast with a carb...but thats an exception lol.
I think your right in that aspect.. the original intake
is better off being dry and injecting at the head
but the drag pack intake was designed to be wet but
yet it should work fine being dry

Do 6.4 heads bolt on to 5.7 blocks? Or will the bore size shroud the valve? (hopefully I am saying that right)....
Also, do they use all the same rocker gear as say an early 5.7, so that it can all just transfer over to the 5.7 head?
Matthew I place one of my Apache heads on a stock bore 5.7 without a gasket. I even posted a picture here on Moparts. But for the life of me I can't find the post LOL
Anyways they do "fit" you would have to notch the top of the bore, IMO nothing major.
The real question is . Is the Apache head TOO BIG for the bore limited block? :twocents

Don't get me wrong, the DP intake isn't anything fancy. It' a compromised intake that in basic design, a carb intake.
That being said, I'd only use one on a 426+ CI motor, 240+ @.050 camshaft, 12:1 compression on 93, 2" headers with heads like my eagles. That would be over 550rwhp from a streetable combination, and it would be perfect to run a 250+shot on.
As a matter of fact, that just may be what I build next...but with the shorter intake. It would be way less trouble than the forced induction on my car.

No doubt that your car is a huge inspiration and it runs. I'd keep the efi and not do much else. I'd even be fine with 1.75" headers on that....
I'd really like to match what the LS7 does but in a hemi. I even thing 600rwhp isn't out of the question with the right combination.
I don't know if you get Hot Rod. they built a Mast head LS7, Holley tunnel ram, dual throttle bodies, cam bigger than mine, put it in that yellow Camaro test car. changed the gear to 4.56 but had the 4l80 trans so they could do that. guess what it ran? exactly the same number as mine and the exact same weight. it had to have $10k more in the engine than mine does, not to mention gear

What MS box has the coil drivers built in for the Hemi? I think the EFIsource ones were having issues.

Do tell? I was aware of the fuel pump relay needing to be bigger and have separated wiring to reduce interference, but nothing directly with the divers not working.
I'm about a month from firing it.

I'm putting my third 3G hemi in my duster at the moment. First motor: 415 rwhp mustang dyno - forged 5.7 .020 over. 218/224 on 113+3. Shorty headers welded by me around factory power steering (now on shelf) Second motor: Bone stock 6.1. Ran great on the road course (TTI's with Borgeson) Third motor: 6.1 based 392. (updated jig TTI's with Borgeson) For engine management, I bought a pre-build MS3x box from DIY Autotune. I use two VW coil drivers wired externally. I've got all the part numbers for the plugs (for the coil drivers). I bought a used factory harness for $150 and spliced it into the DIYautotune harness. The new Holley offerings look very appealing. I don't know anyone running them yet. For an A body, here's what does and doesn't work: Factory Power Steering: nothing works Borgeson power steering: Works:Special TTI's made for this box and A body Doesn't work: everything else Factory Manual Steering: Works: 03-08 5.7 jeep grand Cherokee exhaust manifolds, 03-08 LX exhaust manifolds (requires passenger frame notch - see Gdemon's build), TTI headers Doesn't work: SRT8 exhaust manifolds - any year and model, 09+ challenger 5.7 manifolds unknown: 09+ jeep manifolds, 09+ LX manifolds Factory manual steering with exhaust facing forward (guessing): Best guesses: truck manifold one side (points straight), unknown other side Aftermarket coil over K member with rack and pinion: Works: special TTI's, jeep SRT8 manifolds (requires a few mods), 5.7 03-08 jeep manifolds Doesn't work: LX SRT8 manifolds *If you see a mistake in my A body exhaust list above, please let me know and I'll edit it accordingly.

Efi Source now sells a pre-wired megasquirt kit. If you want to do it yourself, here's the tutorial I wrote: http://www.forabodiesonly.com/mopar/showthread.php?t=226125

What lifters? and what rocker arms? Are they the ones that have a 2k price tag? Last I remember hearing mentioned was that no one is making solid roller lifters yet for the new hemis, and that aftermarket rockers were VERY expensive.
Car runs HARD though Rick! Everytime I see your sig and read about your combo, it makes me want a G3 even more!

I will try to search the post, although it will prbably be VERY hard to find using even the google search function at the top. I would be curious to see how much of a "notch" would need to be made, and whether they are even worth throwing on to a 5.7 bore...Let's face it, if they don't fit a 5.7 bore, then I would render them useful for only a small percentage of builds since the 5.7 is the most common and the cheapest to purchase as well.
