Probe Industries/Coast High Performance has a new pair of stroker combinations for the 3V engine. Both versions utilize a 3.75" stroker crank made from 4340 micro alloy steel, 6.000" long 4340 H-beam connecting rods, performance main/rod bearings and file to fit moly ring set. The pistons are the only difference. You get a high compression version or a low compression version.

High compression: 5cc dish flat top; Stock bore=10.65:1; .020" overbore=10.75:1

Low compression: 12.7cc dish; stock bore=9.2:1; .020" overbore=9.3:1

You can purchase these stroker kits as a rotating assembly or as a fully assembled shortblock direct from Coast High Performance. Price on the shortblocks is in the neighborhood of $4200. Don't know an exact price on the rotating assemblies so you need to contact Coast High Performance. I am about to install one of their shortblocks in my twin turbo car so PM me if you need contact info at Coast High Performance.

There is also a flat top piston available for stock stroke/standard rod length combinations. Yields 10.2:1 compression.
