Piston Shopping
Piston Shopping I am looking at putting forged pistons and rods in my LS2 on the cheap. Piston shopping is a bitch! The only place I've found that allows you to puy the specs in and return something is Summit. I want a stock bore (4.000 or 4.001) and stroke (3.622) piston with between a -4 and -12ish dish. I'll be running stock 243 heads which are 65cc. This is going to be a turbo setup but I'm not willing to drastically reduce compression. I want to target 10:1 but no lower than 9.5:1.
Thunder Racing has some -4cc Mahles for $537 that are on the high side compression-wise but would work.
Summit has some Probe pistons (never heard of them) for $507 with either a -16cc dish (too low) or -3cc valve reliefs for $479.
I've pretty much made up my mind on SCAT rods and perhaps upgrade the bolts in them to ARP 2000's.

There's a -3.2cc flat-top and the 4.000" finish bore is available.

There's a -11cc dish with the same 4.000" finish bore available.
Both are setup for the aftermarket 6.125" rod with .927" pin.

Weisco's would be what I would want if I had my choice so it's good to know they come in a 4.000 bore. A little spendy though. The Mahles are a few hundred less.
When you price a steel top ring set for the Mahle's, you'll spend as much if not a little more than you do on the Wiseco's. Also, the inexpensive Mahle's are 4032 forgings, not 2618. You have to get into the bigger dish pistons to get their 2618's.

Wiseco's come with steel top rings. Also good to know. 
Do you have the compression numbers for both those pistons with a stock 243 head and LS9 gasket? That -11cc might be just what I need. And there's nothing else available in that dish and 4.000 bore.
