I Magnum swapped my '68 Barracuda Convertible and used the stock serpentine belt accessory drive. I chose a 5.9 Magnum, because after doing all the work and expense to swap in the Magnum installing a diminutive 5.2 just didn't make sense to me.
Hotrod wiring has a very nice harness to use the factory JTEK ECM, which I had reflashed to take advantage of the various performance modifications were done. At first, I ran the Summit Headers and later upgrade to TTI's. I used a 1999 Dodge truck with no security for a manual trans model. I got that from Solo PCM's in Florida. I tried a few different tuners over the years, but ended up with Chris at Performance Injection Equipment. He's the best out there in my opinion.
I initially used the truck power steering bracket with a narrower battery and tray, but eventually switched over to the van bracket so get a higher CCA battery. My next phase of upgrades will require mounting the battery in the trunk to get more room in the engine compartment.
For the fuel system, I installed an in tank pump on the factory sending unit and use a surge tank mounted pump to feed the motor. I find this a much better solution than trying to use one of the poorly designed baffled or sumped tanks I see out there these days. This system will flow air-free fuel down to the last gallon of fuel in the tank.
As far as the A/C goes, I used a new Sanden Compressor plumbed to an after market 134-R condenser and a Gen 5 Evaporator. I had custom hoses made at a local shop.
1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

[quotethe] van power steering bracket is a must, or you have to pull the battery to fill the ps resevoir. [/quote]
I put a 5.2 Magnum from a Jeep Grand Cherokee into my Older CJ7 , And the power steering pump is in closer than the truck set up So If you use that front brackets should work in an older car

I did a quick search and just bought a separate van power steering bracket. it bolted right up, but I had to buy a shorter belt.

I did a quick search and just bought a separate van power steering bracket. it bolted right up, but I had to buy a shorter belt. while that is basically what I did, I noticed the shorter belt didn't have a very good wrap around a few pulleys. I discovered that a 5.7 hemi idler is smaller and allows you to use a different longer belt to get better wrap. the path is hard to visualize and I have a hard time putting it back on every time, but it turned out to be a stock 5.9 length, but for a weird application. don't remember off hand. if it doesn't bug you , then it does work without going through that. but I remember hearing a chrip of belt here or there and decided I needed to fix it.

I would keep everything on the magnum just get hoses to match everything up. Get a new receiver dryer for the 134a and do the conversion. Why not run a carb? Also if you find a magnum that is 1995 or older it will have the 46rh(won't need a computer to use it) you can install that also but you have to mod the trans bracket.
