Who told such a silly thing that this motor is not capable for turbos? Check Jesel turbochargerd truck or Blowfish (landspeed record holder)car who took over 2000 hp out of this R5P7 motor with turbocharger.
With right parts and redline limit to around 8500 RPMs you can make 1000+ hp easely. I lso spoke with Steve Morris about it and he told that with alcohol and turbo/turbos some 1200hp is absolutely no problem for such a motor
Good luck and keep us posted. To be honest then turbocharge this motor is in my plans as well...
Here is a link of my friends V6 turbocharged Buick. This motor have a VERY big turbo and that motor produce near 1500hp right now I guess with ethanol fuel. If this little V6 can handle such a boost (over 25PSI) then why R5/P7 cant do it? Just need to have good ECU to control everything and FAST Xfi defenately is the one
This black Buick what made terrible wheelstands is the one what Iam talkeing about : http://www.youtube.com/watch?v=EZYhXc_cR0g
best time so far 7,65sec
I thought BLOWFISH was a 4 cylinder miget engine with a P 7 head.

2 turbos one wastegate. Much easier to synchronize launch boost control. Go with efi. Nobody that has used efi on a turbo would ever go back to a carb, even more so on a street driven car.A carb may be all you need... but it wont be all you want. 
I think I'm pretty set on EFI. Not sure about twins though. I have a lot of room in my engine bay but I think it would be just too cluttered for me.
Maybe someone has some pics of twin turbo setups under the hood of a mopar? I don't want to see non 70's era twin turbo pics. I want it to relate to what I'd be doing.

Ok I kinda thought that was overkill.
What are your thoughts on the open deck?
I don't know much about that but it looks like it can move around under load/boost ??

This is the only part that has ever worried me about putting boost to it. The walls are very thick butI don't know how much it would take to flex it. I would think the whole bank would have to flex and the only way I could imagine it flexing would be up and down. I would think that it would be flexing already at the current power level. Do you think the head and all the bolts would hold the jugs in place?

Few comments, first of all you have A LOT of room to work with packaging 6 turbos in, let alone 2, let alone 1. Nothing to worry about there...
I wouldn't worry about the block at all. 1200hp is sort of a joke. Honestly it would be a waste of a motor that good. You could make 1200hp with a 383/400 and Indy SR heads. WAAAAAY cheaper, and WAAAAY easier.
As trendz said, EFI is nice, amazing drivability, and tuning to the greatest degree. But no one can argue with the fact that you can simply bolt a carb on and go... no tuning needed other then the occasional jet change.

I know the T6 was mentioned as a good turbo to use. I have no idea how big size wise this is. But by your comment I should have no problem stuffing it under the hood?
1200 hp was just a starting point if I can safely go more I will. I'm not scared 
The reason I liked the efi was because it could mange my system better and data log. If I could make big power with a carb I would. I just don't want high maintenance. I like the idea of the computer changing jets for me

I don't have any experience on carb turbo cobinations so don't want to come accross as the athority on Turbocharging but I would really think that there is nothing to be saved in a blow-through system. If you seen a well tuned fuel map and the changing A/F table required to make reliable HP you would see why I have this bias opinion to EFI. Fixing a melt-down is not way easier.
For example, A/F starts at about 13.7 at low boost/vacuum to about 11.5 at 30# boost. Any change to the weather conditions and the wide band O2 will add fuel and potentially save an engine.
