turbo questions I have a 408 iron block, etp heads, 102 fast intake with 11:5 compression. what are my options to make this into a turbo motor? I was told I can't go over 10lbs of boost with a fast intake? Can I keep the compression? Any advice is appreciated.

I've seen more than a few Fast Intakes blow out from boost. Might not be the right choice. LS6 works pretty well.
Compression ratio is relative to boost pressure and octane ratings on the fuel.
Questions you need to ask yourself are:
1. What gas will I want to run? Pump Gas or all the way to C16 (117 octane)
2. How much HP do you want to get up to? Higher HP requires more boost. More boost requires less initial compression ratio given the octane of the fuel.
My buddy has a pure race car that he ran a blower on with 11.5:1 CR with C16 fuel and never had an issue. But get on it with pump gas and KABOOM!
So give us some detail on your goals. Maybe we can give you some general direction on this.

I would like to make around 1000hp, i was told to go with a 85mm turbo? So i called f.a.s.t today and asked about the boost issue and I was told that they have gone up to 60lbs of boost and had no issues. I would prefer to use pump gas. It's gonna be more of a street car than a track car. I think it would be cool to keep the a/c on it. I just don't want to put $15,000 in the car to get there. Single turbo or twin? Thank you for the help.

From my understanding, the early FAST intakes were what had an issue with boost, later years held up much better. We had a 102mm on our mile car 416ci. and ran it up to 15psig on the dyno with no issues from it.
If E85 is readily availiable to you at the pump, that would be the best solution to the higher compression of your motor. If not, a set of heads with a large combustion chamber or a set of dished pistons are in store to make big/safe power with boost.
