Forged 20s/Michelins/HD FE4/HD Diff/HD Trans/6-4 Brakes (as upgrades, NOT replacements) will add approx. $7,000. Crate LS7 - crate LS3 = $7,000, as per GMPP.

Actually, the LS7 sells for LESS, slightly. With 80 fewer ft-lb, and the same driveline, the LS7 will prove to be more warranty-friendly, though...

If only... As defined throughout this thread, figure mid-$40s...BOSS LS-correct/competitive. Add for MR ($2-2,500, as a substitute), add for coolers...
