I bought a 393 stroker kit from DSS, crank pistons, rings the whole kit. I upgraded the pistions and rings(the rings were suppose to be ductile iron. I bought canton oil pan from them and Tom seemed very helpful.
Problems:
1. Being that I am a Toolmaker machinist I checked the upgraded pistons with a micrometer. They varied as much as .004(not good) And to upgrade to these pistons cost me 500.00 bucks. Had to send them back to get pistions that were the same diameter.
2. This one is the one that scares me. I upgrade the rings to ductile iron rings which was an added 75.00 more. I needed the better rings because of the boost I am planning on running(eventually between 20- 24 bls of boost). The rings they sent were cast iron(they would have broke like crackers). The only way I found out was that my engine builder call me at work and ask me to come by. He told me he did not believe they were ductile iron, so I told him to break one. That is one way you can tell for sure. It snap in three places(Sh$t cast iron). I called Tom at DSS he wanted to give me the run around instead of just replacing the rings. Saying the rep would have to credit him first before he could help me. Seems to me if you have drop 2800.00 to DSS why would you quabble over a set of rings.
So I will replace the rings myself, just to avoid the frustration and move on.
