Progress update and photo dump!!
After some trial and error with parts, I finalized the serp belt drive. Belt is a Gates K070553
I used a ribbed idler pulley, Gates 36222, from Oreilly. It came with a center bushing, but the interior diameter of the bushing was too big, so I used the original center bushing and it worked perfectly.

Bypass hose is a Gates 22038 (factory hose for magnum)
Getting ready to install the assembly. I found that, once in the air at the necessary angle, the alternator bracket was going to touch the hoist's lifting arm, so I removed the alternator and bracket as an assembly for clearance, as you can see the following picture.
.....and in.
I purchased the motor mount brackets from Barry Zepick almost a year ago on FB and original style 273 isolators from Ebay. Engine fits perfect with this combo and the passenger side bracket fits all three magnum block ears.
With the hoist out of the way, I reinstalled the alternator/bracket/belt and was able to install the FiTech throttle body to begin routing the harnesses. (Ignore the isolator in this picture, it was the wrong one and used just for mockup)
Finished cleaning up the Fitech harness and alternator harness on the passenger's side. At the time, I had not received the cluster gauges(and I didn't stop to think that I still had to add the temp sensor harness, so I will have to open up the harness on the intake again to tuck it in)
I'm using a 22" radiator from ECP,
22″ Mopar SMALL BLOCK HD Aluminum Radiator | ECP and a fan from RockAuto. The fan is for a 2008 Chevy HHR 2.4L,
More Information for TYC 621450
I modified the fan by removing the ears off the top and bottom for a more flush fit, as well as cut off the mounting arms on the sides, as they extend passed the radiator and are not usable. I will drill small holes into the shroud and go with a pass-through method for mounting.
At this point, I received the gauges and you can see the new coolant temp sensor harness next to the throttle body that I will incorporate into the FiTech Harness for cleanliness. I was also able to install the radiator and verified that the fan fits correctly in it's place. I will snap pics of the clearance once permanently installed. I also fully installed the throttle cable and started installing the kickdown cable. Not attached to trans yet. (Also, still have not cleaned up the driver's side harnesses yet....)
I took advantage of Black Friday sales at Speedhut and picked up these 4.5" gauges. Combo GPS speedo/tach, and a 4 in one Fuel/Volt/Temp/Oil. I did have to enlarge the opening of the cluster bezel just a bit to fit the housing of the new gauges in, but overall they are about the same size as the originals. I'll get some more pics of the wiring and install of these as I progress. I will be painting the bezel first, though.
Hope to finish cleaning up all the engine bay harnesses this week.
