Katech "Value 427" short blocks
Do you have any of these that are not already assembled? In other words, can I buy just the rotating assembly at a comparable savings? If so, what is the price (balanced) with LS7 pistons? (Just bought an LS7 block)

No, 4.125x4.000 is the max bore/stroke.

Would I See Any Benefit From Droping This Into My Otherwise Stock 2004 C5? Or Would The Stock Heads/intake Choke It Off And Not Make It Worth The Effort/cost?
Also What Needs To Be Done To Make This Work With The Stock Engine Computer (besides A Tune) I.e. Knock Sensor Issues Etc.... So The Smog ****'s Here In Cali Are None The Wiser On The Visual?

AFR 225s or comparable head would be better. 205s might hurt your top end power. I'd be taking a wild guess at your rwhp number.
