Well the local machine shop I use charges around $500 for all the machine work, and balancing you will need to have done. This is included a align hone, bore and hone, tank, clean, freeze plugs, cam bearings, and balance the rotating assembly (this is $200 of the above $500).
A stroker kit will cost you around $1100 for a cast assembly and $1500 for a good 4340 assembly. If your interested I have a 4340 331 kit balanced for sale that has 650 miles on it, only reason it is for sale is we went to a DART block when we upgraded the blower to a YS-Trim and decided to go internally balanced so we buoght a new Eagle internally balanced crank, however it has different rod journals so the rods could not be used either so I put the entire kit up for sale. I am asking $1300 (this is under whole sale for the parts, and it is balanced) for it and this will included brand new rings (Total Seals file to fit) and rod and main bearings (Clevitte h-series bearings). Parts are in pefect shape, guaranteed. I also have a alum Fluidamper balancer asking $275 paid over $400.

Now as far as D.S.S goes I only have one expierence with them. I had a customer bring me his 94 Cobra that was having issues on a low mile DSS Pro Comp 306, the tolerances were all over the place and the align hone looked like it had been done with a dull spoon. I know others that have had good luck so it is half dozen off one and a dozen of the other. I just built a new 331 for the Cobra using a cast SCAT kit, which I have put a few of those together wil no issues...same goes for the 4340 kits.
