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.
