It's finally coming together. Up close pics of the shortblock are below. It's bored .040 over, has stock rods with ARP bolts, std pressure & volume oil pump.
The pistons are forged TRW L2455F flat-tops of the "2300 Pinto" variety, the 4032 alloy. They have a round dish milled in them to get compression back into the 8:1 range, exact compression hasn't been calculated yet. They were milled by some Ford guys my machinest knows out in Ohio, they didn't think the D vs. an O shape to be a worry. Since this isn't a race motor and I'll never push it that hard it shouldn't be a problem for me, it probably shouldn't be boosted to hard since the block's at 40 over anyhow.
Milling was $140, pistons were $300, rings were around 70. So that's just over $500 for all of it, around the same cost as the Diamonds or CPs but didn't have to wait for them.

I read over at Turboford that the stock pistons in the 2.3T were of the 4032 alloy, here's a useful article on the two types of forged aluminum alloys used in pistons:
