Consider what Tim said!
Also, the weight of the block shouldn't be a factor over strength in a boosted application
Just for refernce:
stock GM "LS" aluminum blocks compared to their "Vortec" counterpart iron blocks is only approx a 75lb. difference
And and good builder (ones that I deal with also) usually recommend a GM iron block or quality aftermarket one as Tim suggested, when dealing in boosted applications
If you want to read up on a bunch of stock LS7 block failures under boost, head over to the Corvette forums and grab a drink, you'll be there awhile!
Not saying that there are boosted aluminum blocks out there (ie alot of Gen5's running s/c's)
plus it depends on, as asked, intended usage, boost level and as always Budget!!
