It'll hang with the blower. Only issue is sealing. Some of these builds seal to the heads, some don't. I'm at the same place with my 427 build. I understand the LS6 block is a better platform than the LS3 block too (bore concentricity issues). LME is a reputable company. Wouldn't think you'd have trouble with thier engine. LS3 heads ****** ROCK! Definately envy you. hahaha
