Need help buying Pistons...
I just got off the phone with Wiseco and the tech on the other end told me that the piston for a LS6 running stock control arms is a 3.899 diameter. He also told me that my compression ratio would drop from 10.5:1 to 9.7:1.
This guy did not seem very sure of the info he was giving me so I'm very sckepical at this point. My thinking is if the compression is decreased to 9.7:1 then when a machinist machines your head then the compression ration will raise back to normal 10.5:1. Tell me if that make sence to you all.
Also, how many cc's is our combustion chamber rated at. That also was a question he was not able to answer. The piston he was selling is at 70cc's.
