First, I suspect y'all have gotten excited about doing this due to soem "makes it look easy" Saturday morning car shows? Like there's nothing to it at all, the way it looks.
Originally, the Gen III Hemi had a carburetor intake and electronic ignition system capability. Saw one like that at Mopar Nats that first year! Yet with the Mopar Perf wiring harness kit, those production items (EFI and ignition) stay in place. On his conversion, the stock suspension was intact! I do believe he added a Borgeson steering box to replace the larger Chrysler unit?
As you might know, the radiator core support mounting for the radiator is flat. What he did was to cut the radiator support area out of the salvage yard Charger, cut off the top, and then BOLT it to the existing core support on the Fury. Then he found the most-HD radiator for the Charger 5.7L Hemi cars and ordered one for about $150.00 or less, NEW. Then he just had to find some radiator hoses to connect the radiator and the engine, with a section for the filler cap on the upper hose.
Seems like he got the bracket kit from Bouchillon?
So, NO real need to cut-up the car to do it! Just make a few minor changes to the existing architecture. KEEP the torsion bar front suspension, TOO!
I realize that it's somewhat trendy to put coil-over front suspensions on Mopars, for allegedly better ride/handling, BUT considering what it takes to do that, unless it's a complete bolt-in front structure, you can ruin more than you're seeking to improve. PLUS build more things to "make right" in the process. Think "money pit", at least to me.
Not to forget that what made these Mopars the great road machines they were was the torsion bar/leaf spring suspension and its suspensioin dynamics. As trendy and the OEMs are with their almost-universal use of coil-overs now, NONE of those vehicles ride as well as a Chrysler torsion bar/leaf spring suspension with a good set of HD shocks -- period. I'm not talking "soft" in the GM or Ford sense of things, but "firm" in the Chrysler sense of things.
So, with all due respect, anybody that feels they need to completely alter a Chrysler front suspension just to say "Look what I did!" and "Here's what else I had to do to make it work" is an expensive way to keep themselves out of trouble?
Perhaps I'm looking at things with an eye toward ultimate resale, too, but with such major modifications, the ultimate (later) buyer pool will diminish greatly. No way to recoup the $$$$ spent either. Which to me, means money used which could have been used to better restore the car in the first place. Plus, once you take away most of the Chrysler engineered items which made a Chrysler product a Chrysler product, it soon becomes a lesser product, to me. MUCH easier to modify a full-frame Ford or GM vehicle in the manner mentioned.
Sorry if some might disagree, which I respect. Your money, your dreams, your vehicle.
Enjoy!
