You guys are making this way more complicated that it needs to be.
1. Drop block, rods, and pistons off to the machine shop.
2. Tell them to make the pistons fit the block.
3. Have them clean the block and prep for assembly
4. Pick block up when done.
Never order bearings until the crank is polished or ground....

I ran into this with a 408 I am building for my truck.
Dropped the block, crank, rods at machine shop.
Had 30 over pistons picked out. (But not purchased)
Ended up needing 40 over due to a cyl having a deep score in it.

We understand your point very clearly.
Here is the other point trying to be made......
Going from a stock 3.780 bore to a 3.898 bore is "118 over". So there is no need to wait to buy pistons unless your block takes more than 118 to clean up, in which case you would have to get another block anyway.
IMO in these cases it is good to have your pistons supplied with the block so that they can machine the block to fit the exact pistons you purchased.

Sorry. Guess I was not very clear. My point was that I try to buy pistons only after the block has been prepped. You don't want to buy pistons only to find out the block will require a larger than expected clean up.

Caps are marked from factory. I was careful with the rod caps also.No way Im going to assemble the shortblock gave me a price of $200 which I think is really fair.

When you build an Iron 5.7 Block you need to be sure the 5.3L block can take that much boring. Some blocks have core shift and can not be bored that much. The only way to know is to have it sonic checked. There have been a few members that decided to bore any way and ended up with a scrap block.
So in other words wait to buy the pistons until you have the block checked out. Some companies will not accept returns on Pistons at all. Others may charge a restock fee.
Phasemaster, if your comfortable with the price and the shops work, then go for it. Some of the required tools can easily cost the price they quoted you.
