This is what I found:

“Piston to Bore Clearance-

0.010-0.041mm
or
0.0004-0.0016in”

Here is the link (HTML link) to where I got the information. It is for a 2007, but it is still an L61.

I hope that helps.

that is for stock pistons, wich will be way to tight for wisecos. the last motor i built was 0.0025" piston to wall, that was ideal for a street/strip motor. this is whats recomended by wiseco. in a race only motor id open up to 0.004-0.006"
