Eagle rods are 500 bucks huh? Interesting, cause Eagle list them on their website for 400, but if you were smart and looked around you would see that they are anywhere from 275-330 dollars from just about every car shop in the united states. Here they are for $320 shipped:

By "sleeve brace" I am gonna assume you mean "block gaurd" which is 1. A waste of money as it does more damage then good and 2. $95.50 for a golden eagle one, and even cheaper for other companies.
ARP's for a LS are 100 bucks, hell I paid 130 for my GSR ones which are more expensive for some damn reason lol.
ARP mains are about 100 so ill give you that (did you have your block line honed? It will need to be if you run the arp main studs, just a heads up)
SRP pistons: $479 (I know mine were cheaper then that when I bought them for a D series):

I'll give ya the 250 for shaving, cleaning and boring cause machines shops aren't cheap. I'll also give you 200 for the crank, but even then thats high since most times you can pick up LS cranks for 50-100 bucks.
Do the math and thats under 1600 bucks lol. Like I said, you are getting raped. Search the internet and find the best deals to save you some money man, don't pay twice as much as what its worth!!
For 3k you could've gotten a much better setup, thats why I said you got ripped off. For instance you could've gotten something like this:
Benson sleeved block
Benson balanced and micropolished crank
CP pistons and rings
Pauter rods
ACL bearings
OEM (TypeR) oil pump
Lower gasket set
Blueprint and assembly
Boxing, return shipping and insurance (lower 48 only)
Total $3450
Eagle rods substituted for Pauters...$3050
Or how about a very similar setup to what you have listed
Economy build (no sleeves, bored to 81.5mm) with CP's and Eagle rods...$2350
See why I say you got ripped off? Not bashing your setup, just bashing who ever is raping you for money!
