i'd recommend a stock LS1 block, std. bore. an ls1 can only be bored .10 over before having to be resleeved which get expensive, and with the LT1, i wouldn't run much boost on it .60 over(thats just me).

the LS1 is a very tough motor, i wouldnt doubt the aluminum or make iron vs. aluminum an issue. Many spray and have supercharger setups on stock bottom end without many concerns, if you upgrade to better internals, itll be just as strong as a built lt1.

As for an LS1 build, i'd suggest stock displacement(346cu. in.) and go with a serious heads/cam package, throw on an LS6 intake and you'll be in the 11's with a proper suspension setup.

True duals arent really a viable option on a 3rd gen, its do-able but theres no need. An 500hp LS1 can easily make due with a single 3" catback.

Also since it'll be custom and so on, tuning an LS1 would be much easier.
