    couldnt find it. I know wisecos used a bigger clearance due to the forged piston swelling more.

    Thanks Rich, I tried to call them when I got off of work but they were closed already. I bet they will say like a radical .003 or something. I feel that is too tight. Let me know though......
    Thanks again.

    6 or 7 thousandths...5.5 or below you will Seizeco them. You can even put them into your oven on 250 degrees for 30 minutes to help "shrink" them in before install.

    Dunno if that actually works great or not...but I was told to do it to help...I've done it ever since.
