ls1 or 6.0

got a 1999 c5 a4 geting ready to upgrade motor trying to decide if i should go with the ls1 or go to a iron 6.0 block. i have a 150 nitrous express kit on it right now and want to go back with the same kit. will be using the ported and polished ls1 853 heads, ls6 intake, nitrous cam, and a 3200 stall. has any body went with this setup before. or have any suggestions. and i dont road race just drag race and play on the street.

Tuff choice, iron block better for nos but heavy, obvious, will hurt handling. Heavy block slows car down offset by more displacement.
If it's for mostly drag racing I'd say go big. Good luck
