Uh......okay....well first off the stock bottom end with studs WILL hold up to 10lb boost but if you are serious about this you are going to need a kit like what I got (SCAT 4340 competition grade 408 stroker) in the stock displacement.
Next you DON'T want a large cam for FI anyway, something mid-sized with minimal overlap is best otherwise you are wasting boost.
After that you must MUST MMMUUUSSSTTT get the computer reprogrammed and equip at least 36LB injectors to back up the massive BFSC need of a turbo engine.
Lastly you could go to a junkyard and find a pair of smaller turbos (like something off a V6 or large I4) and have custom fabricated adapters made to mate them to your manifolds. Always remember to intercool any boosted application and have a proper blowoff valve and wastegate. Something else to think about is an old cummins turbo diesel turbo instead of two small ones, will be a hell of a lot more top end but with more turbo lag.
