Whats the absolute best suspension for the mopar?
67-74 A Body
Is it Alterkation and Street Lynx rear or leafs and Hotchkis components
The car will make 800+ hp with a paired small turbos
Tough question to answer satisfactorily based on just this information. More relevent info would be track types, race types, sanctioning body rules, etc. "Best" largely becomes dependant upon those three conditions rather than body style or horsepower levels.
With a pair of turbos, I'd assume it is an open track day exercise with no governing body or rules restrictions, therefore anything is possible. Do you plan on tuning the suspension or just bolting it on and hitting the tarmac?
Bolt on stock replacement stuff that refines the OEM design can be put together for around $2500-3500 complete on both ends. Stepping up to lightweight frame members, coil overs, or air spring arrangements with multi adjustable shocks will start around $4500-5000 per end of the car.

Very open ended question.
Would be like someone calling Indy and just asking one and only one thing, "What is the absolute best motor for my Mopar?"

Ride good handle good do donuts good.... just an all around real fun car
Give us an idea of your current knowledge on how to build cars so we know where to take this. Building what you are describing would be breaking some new ground in the Mopar world. It is very difficult to build an efficient handling car with a twin turbo 800 HP combination on an older chassis platform.
Sounds fun though.

Breaking ground by taking that comment literal to driving 1000+ miles at 200 mph or just runing up to 200 mph at points like Siver State Classic type stuff?? While having an all around car. By that, I agree.
But, I don't know how to interpet that comment myself.

The stock suspension will work pretty well up to about 150-160 mph. The biggest issue is that you run out of suspension travel when you lower the car. The car needs to be lower for aero as well as CG and looks, but the torsion bar setup doesn't have much room once you lower it. Other than that issue, the double wishbone torsion bar front and the short front leaf rear suspension is a good combo. Good enough that TA and NASCAR used it for a long time. Tim's Valiant has about all the tricks necessary for high speed track days. Eberg's Brick doesn't have quite so many tricks but it stills hauls the mail. I'm not aware of any A-body with tons of tricks that works better than either Tim's car or Eberg's, but they could exist. I certainly don't know about every A-body Mopar in the country! Here is one article on Tim's car. There are several more in Mopar Muscle. Just go to the MM website and search on my name. http://www.moparmusclemagazine.com/techa...ep/viewall.html

Well leaves are out with that kind of power so figure on a Street Lynx tri 4 bar type or an Art Morrison watts/3 link would the cats ass IMO. Some big T-bars,swaybar, Hotchkis Fox shocks or Ridetech adjustables up front. Which A body? Tire selection isnt the same across the board for all A bodies so that is another thing to figure in. I have 275 front and 335 rear tires on my 72 Dart and think a 285 could fit in the front with some steering limiting.
Mopar to the bone!!!

Although in my experiance, off the shelf full length headers will be the limit of lowering on the street before the suspension. TTI and Dougs included.

With that in mind you may as well talk to a chassis builder that is building NASCAR cars and build a full frame car. Tim's car certainly "an all around real fun car" but he would have to comment about driving it @ 200 on the street, though I have my doubts about the areo on any old car short of a Superbird. There was someone that built a 2nd gen Barracuda for a high speed run and ended up changing the nose completely- ended up looking like a late Firebird. It was in the usual car rags a few years ago. The classic a-body noses are too high for good areo.

With a pair of hairdryers, full length headers won't be a problem, though getting all that plumbing in an a-body will be another issue.

Forgot about that. Good point.
Just hope he doesn't have any plumbing lower than the plane of the bottom of the K-member
