I had been thinking this, as i have a 300c srt engine it has the oil cooler. Was thinking if i run the earls remote cooler i could fit this in the remote area........having said that i am trying to tidy the bay up lol. One of my friends runs a performance shop and said the oil coolers are a good bit of kit and defiantly worth it

That would be the oil cooler that plumbs into the radiator hose and uses coolant to maintain a consistent temp. The one @Dantra has is like the Hellcat setup where the cooler is completely separate and plumbs to an external cooler that uses ambient air. They put the oil cooler like the 300 SRT one on the 6.4's and HD 5.7's in the trucks so they must be worth something, but the setup off the TRX is the ultimate and probably more like what you friend is talking about.

That said, I have one of the coolant type oil coolers and have wondered if I could fit it up to my 90 degree adapter but haven't messed with it. Kind of doubt it will fit though.

OOooo ill have to have a look. I like to mess about with that kind of stuff. On my ute i used a standard oil cooler solid line type to cool the power steering oil. As if doing track work the commodore tends to cook the oil....... not that it ever seen a track lol.
 
The coolant type oil coolers are pretty common. Vipers use them and I believe the same exact cooler is used on GT40s and other cars. They are nice and small, so pretty easy to mount and you don't have to worry about airflow with them. Maybe not as much cooling potential as an air type, but if it puts up with what Vipers can put out, I'm inclined to believe it's fine. Granted the Viper also has ~11 quarts of oil to dump heat into, so it may not need the same kind of cooling.

Looking forward to seeing that trans cross member and tunnel come together. I hammer and dollied that driver's side bump flat where the auto trans console linkage come through on my trans tunnel. Gives it a nicer look!

Me too! But right now it feels like a festering sliver I can't seem to get out of my finger. Struggling to make progress on getting it sketched out.

Ugh! Now you have me looking at Vipers again!

I have to agree if they used it on the Vipers, must be useful. I did some looking and it appears the '02 and older ones used a remote air cooled type, but all of the later ones used the plate style with coolant.

The Viper one and the 6.4 car cooler look to be better than the truck cooler. The Viper and 6.4 ones have some external cooling fins and are larger while the truck one is just a pot for the coolant to flow in. After looking at it some, makes me want to try and see if the 6.4 one would fit on the 90 degree adapter and clear everything.

Not a guarantee, but a guy on FB was able to fit the low mount alternator without trimming his frame rail. It was a Powermaster, so maybe the stock one won't work? Time will tell.

Those are nice.. pricey tho. I really didn't mind trimming the flange and in hindsight, I wish I would've trimmed mine all the way to the core support. I still might. It makes for a better fitting LX radiator.. I had to roll the flange down to get the radiator to fit. I just cut the flange flush, making the frame rail a square 90 degree edge and then just welded the corner seam together. It's not bad. One advantage is is oem fit, so if I ever have one fail, it's a shelf item.

I saw this before on the early 5.7 car covers as well. Some people dropped them in no problem and others had to trim. No one mentioned any aftermarket alternators specifically, so it's possible the factory might have offered some different ones. Like maybe a higher output one for police applications with a lot of idling or something like that.

There are definitely some different sizes depending on vehicle. My 6.4 is larger than my 5.7

In my case, I can't use one since I need an OEM alternator. But based on the case, I am going to guess it is an OEM one Powermaster modifies.

I know the amp output varied and went up as they got newer, and I think the bigger output makes the case bigger. My hope has been to find a smaller one that fit without cutting the flange.

Can you get this alternator from Summit/Jegs or is it exclusively through Bouchillon performance only?

Not sure. But found this one on Summit:

Good info. I plan to run an LX radiator as well so I will pay attention to that when I get there.

I'm not so worried about cutting the flange on the '73. I wasn't excited about doing it on the '74 when that was the car the 5.7 was going into but now that I have shifted it is less important. But, if I did end of doing the swap to the '74 later, not having to cut the flange would be a huge bonus.
 
Lots of good information here. I'm another one that was thinking of running a stock LX radiator. Are they all the same? Do I just pick a 2005+ Charger or are there specific years that are preferred? I think I read somewhere there is a "heavy duty" version as well.

I grabbed one out of my buddy's junk yard. It was out of 2013 Police cruiser. Scrapyards are the best way in my opinion.. because then you can grab the lower support, upper mounts, all the rubber seals/strips etc. That stuff gets expensive when bought individually. But I believe the interchange doesn't change much across the years.. see alot of the same part numbers for SRT, RT and SE but there may be a difference between pre eagle and eagle. I think the only differences were fan options.. I'm running the dual fan.
 
I haven't looked at radiators much until now, but there appears to be two levels to the radiators based on the Mopar part numbers available on RockAuto. Spectra lists 3 different options with core thicknesses of 7/8", 1 1/4" and 1 7/16". The core sizes seem to vary some too, as do the listed inlet/outlet sizes so not sure how accurate the info is.

The radiator hoses seem to be consistent provided their isn't oil cooler connections and not an HC. There does seem to be a split around the time the Eagle and 6.4 were introduced when there are oil cooler connections, but guessing that isn't related to the radiator.

Fans are a mystery. All of the wiring diagrams I have been through seem to show a dual fan setup for 5.7's, 6.1's and 6.4's while the HC got a single fan. But the offerings on RockAuto make me wonder if there wasn't a lower duty single fan option, maybe for the V6 cars?

Based on this I will be looking for any year radiator with the thickest core I can find and dual fans. I would prefer the single fan HC setup just to make the fan controller simpler but those fans seem to go a for real money.

There's a few aluminum ones on ebay too, that have caught my eye. I'm pretty sure the one I run has the thinner core.. but it runs cool. I saw it touch 210 at Moparty after some hard runs.

I would have expected the Pursuit cars to have the thicker one. But just a guess.

How many fans?

One thing I have to figure out is the fill cap. I like the idea of keeping the cap on the radiator but there are no options to do so with the LX radiator. You added a cap in the radiator hose, which is an option, or maybe an expansion tank like the stock setup in the LX/LC cars. Not sure which way I will go yet.
