My question is: If you were going to build a tube chassis car, and had pretty much no parts at this time, would you build a 500+inch wedge or a gen III Hemi? Max horsepower expectation would eventually be about 900hp, but not for a few years.
I'm a old wedge guy from way back so my choice, based on personel expereinces would be the 500+ C.I. wedge, probally 4.500 bore by 4.250 stroke with a new race block and a real good set of heads, B1 or Predators.  You really should make a decision on which motor to use before buying any partsThe new Gen3 Hemi have the potential to make a lot of power also  The choice is yours to make

Good question.
Are you considering a ProCharged, or supercharged Gen III?
I think it will still be cheaper and easier to build a 511-572 CID, B1 headed, big block wedge. Get a 4.500" bore World (MP) block (aluminum if you have the money), 4.25-4.50" stroke crankshaft, and some B1 original heads and you have 900 hp for roughly $15,000.
But the Gen III would be really cool, light weight, etc. And I think with a small ProCharger or supercharger it could be the future.

If it`s your "bucket List" car, why not go Gen II Hemi ? I did , and have never regretted it .

Old BB stuff is cheaper and easy to copy someone elses build , HOWEVER if I could sell my 3-race motors and my 11-spare 440`s/parts etc.... I would be building a new HEMI with a pro-charger like tommorrow!!!!!!!  I`ve been intrigued with the new stuff for quite a while.  To me the old stuff is just that "old". Either way do what you think will satisfy your needs.

If your goal is 900 hp in the future, the cheapest route is to start with those parts. You can do it with B1 heads, or 572-13 heads, or even 440-1 heads. But the latter is going to require that you have all the tricks to get there. that equals $$$. My cheapest recipe would be to locate a used set of B1 heads that flow well ( good porting work) and put them on a 540 557 or 572 shortblock. The deal won't have to be real exotic to get 900 hp.

That HEMI was a heck of a deal, dirt cheap!! 
I would go with the new Gen 3 HEMI!
people have proved its not hard to make the power with them.
I regret building another LA motor instead of the newer HEMI!

The chassis for this project is to be a light weight tube chassis (Dave Morgan would call it a ballerina)...RX7. Yea, I know it's not a mopar body, but it was free, and besides that, it should be good for aggravating the ricers! My ultimate goal is to run a 7.99 et, hence the 900hp goal...down the road a few $$$$. The Gen III Hemi looks to have a lot of potential and I think it would be cheaper and lighter than a Gen II Hemi, or at least smaller! That's why I'm looking for opinions
The Gen III would be cheaper and lighter/smaller than Gen II. They do make some good power adders for them now. You going to run it N/A? Boost? Spray?

I think in the long run it would be cheaper and make a more reliable car. With boost you don't need to wind the pee out of the engine, use big lift cams, huge stalls or tall gears. My buddy runs a Plymouth TC3 (omni) chassis car. He has a W5 headed 392 SB. He uses 10-12lbs of boost (big turbo, no inner-cooler) 4200 stall and 3.73 gears. He has run 8.20's at 175. The car could run 7's if he jumped up the boost and wanted to use the trans brake.
