I'm all for bigger but aren't the L92's known for liftin? too thin a deck for boost? I'm under the impression they're great N/A but not so much for boost. just slap some 427 stickers on the fenders and call it good... 
The L92's don't ned much boost to make power, BUT they seem to be prone to gasket failures over about 750rwhp.
I made 737 through a th400 at only 12psi, so if you are looking for 700rwhp as a max you should be ok presuming the shortblock holds.
Forged pistons and rods are a good idea, but many have had stock shortblocks hold at that power for a seasdon or two.
If it were me, I would just get a less expensive regular old 6.0 and use the money you saved for forged internals, because the 6.0 heads hold up a little better anyways.
Good luck!

Get the truck 6.0 preferbly the 02 or later. The lq4 has 9.4:1 compression and the lq9 has 10.0:1 compression. Pick which one you want. The pistons are the only difference.
98z28cobrakiller has gone 10.08 with a stock lq9 with an 88 mm turbo.
As far as the l92 motor you would have to get rid of the lifters and it is recommended the you change the oil pump because the VVT uses a higher volume oil pump and you won't need that in getting rid of the VVT. The motor will make some decent power under boost. As you can see though it will cost you a little money up front to put that motor in. It would probably be easier to use the lq4 or lq9.
