I estimated over $20K just in parts in the other thread from a few weeks back and I didn't know they were converting to rack/pinion or going with 13" rear brakes. They went with a 9", what's wrong with the explorer brakes everyone uses.
I could spent $20k on a G-Body quite easily, but that would probably include a paint job and a custom interior.
For the particular build they are going with, the Day 1 stuff was almost $15k alone. With that price, you can just add $5k and get a brand new Schwartz chassis with everything assembled for you (brakes/suspension). I'm not sure why you'd pay $8k for a SBC with 500hp. That's the price of an LS3 with everything included down to the pedals from Summit.
I definitely understand buying everything new, but geesh.
