$16580 These items only.
Does not include gaskets, fastners, etc. Total bill for parts was $17,931.88. Obviously, I got a bit of deal on some of the stuff (Velasco crank, heads), while other items are off the shelf costs.
Labor [Build/ Major Head Work (4400), balance (135), test run (450), etc.] $5075 Obviously, build costs will vary significantly depending on what is done to the block (Shelbys do need some work) and the heads for increased flow.
I paid 22,526.38
plus the scattershield, remote
oil filter adaptor, rear puke tank fitting for manifold, water pump, pulleys, etc.
Throw in some freeking tax, and that's how you spend $25K real damn easy.
Hope this answers some questions. You don't have to spend what I spent--many alternatives for parts, and some of the labor (heads) depends on what you want. I still think you need to figure on around $20K for a Shelby-based motor.
