Stick with stock crank, eagle rods, JE pistons. Will make 650 all day with nicely ported heads. Just run a large enough turbo to keep IAT's and max efficiency up. That will allow you to stretch the setups legs a little more.

I went with the 383 eagle crank(needed for more power in the future), H-beam rods with -20cc diamond pistons and pro seal rings! FI custom cam and 243 LS6 stage 2 heads with a D1SC @ 12psi help make the extra power!
EPP made 715rwhp on a mustang dyno(14psi)with a simular setup on a 347!I let you know what I get with 12psi!

I think the bottom should be balanced to the heavens. Many options on rods, pistons and rings. What about heads?
Can I get dibs on your ls1 block when finished?

Sure..didnt you get some IForged rims for your car? where are the pics if u did?
pics JOSE? Would a 76 with .96a/r have much more back pressure with a ls2 (364 right?)
I see alot of people running 76 .96a/r on a 346-7

damn..i wanna get some iforged rims sooo bad
What kit you planning jake? Just upgrade you block now if you just want a 346. Or it gets honed .010 to a 347. I think speed inc's new twin kit would for sure make the power you want and streetablity. ls2 might be pushing it on back pressure. I'm sure the pros will correct me if I'm wrong. Thanks guys

Go with a 76 with either an MPS turbine or GTS turbine. Stick with either a .96A/R or as close to that as possible.

Go 347, and the stock crank has already proven itself to 1000hp. No need for expensive cranks unless you just like spending money. Matt H. proved that already.

Plus, Jake the LS2 would be worth it for 1200+ HP and going at least 364 on the cubes. Otherwise your going to hit 650 with no problem. I believe also the LS2 in your camaro you have to extend the wire harness and a some other stuff that really dosen't make it worth the $$$. Save your money, go turbo AND get some Iforged bling bling. 
Don't forget fuel that **** adds up real quick.
