I don't know about hp/tq #'s, but I'll gues high 12's in the quarter mile. Sounds fun and I'm officially jealous.

Just want to make sure you are clear on what Z06 heads 243 castings are.. They are the Gen 3 motor heads, not the 427ci LS7 Z06 heads. Sounds like a decent little combo.
|
doesnt your motor come stock with an ls2 timing chain? my 07 classic did. id check it out before installing it because you might waste som time getting the sprocket off the crank, which i find to be a PITA. nice combo by the way, you gonna get it dyno tuned?
