I have the invoice from the last owner of my car...he paid $5,600. It was built to stock specs. Parts include(off the top of my head): new pistons, cam, valves, pushrods, etc. Oh, and he had stuff like the AC charged and the new fuel pump installed. I'm not sure if this guy got raped, but I know I don't want to spend that much if I ever have to rebuild.

Generally Speaking, Look at about $1,000./100hp in the engine. The cost will vary with options like Girdle, piston quality,ARP hardware used, and other such upgraded. We have built Long blocks for as little as $2,500 and up to about $5,000+. When pricing out the job, compare what each is doing, not just the parts; ie Bal. & Blue printed, oil mods. and more.
I saw the article in GM High Tech and wanted to compare their prices with others out there. They do alot of nice oil mods and stuff but man thats alot of money. Looks like you get what you pay for. Thanks
