Need help buying Pistons...

Hey,

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.

HELP!!!!!

Something doesn't sound quite right. Have you checked to make sure you don't have to bore the cylinders before the new pistons go in?

LS15 Power! LS2 + LS6 + LS7 = LS15.

Re: Need help buying Pistons...

I wasn't clear. Did your machine shop inspect the bore for any problems that may cause you to overbore the cylinders?

I'm doing the honing on the cylinders my self and I inspected each bore and gauged each one and they are all with in spec. I do not need to overbore them.

What I need is a set that will fit the stock size bore (3.898) and be used with the stock control arms. Also, it needs to retain the same compression ratio of 10.5:1. That's my delema.

I think there are quite a few companies that make them but I have a friend that does a lot of LSX work and he favors Mahle. Most online parts houses sell Mahle.

LS15 Power! LS2 + LS6 + LS7 = LS15.

Piston update...

I pulled the trigger on some Mahle pistons today. I'm starting to see light at the end of the tunnel. Now I just need my fuel injectors retooled to put out 36 lbs and get my heads back for the valve job and I can start re-assembly. I should have it done early next year. That of course is assuming the world is not ending on the 21st since the myan calendar is ending. Lol
