i have a ls block that is bored .02 over. what size pistons and rings should i use. i plan on boosting the motor i build (only 7-10 psi). stock size pistons, with larger rings? or should i get .02 over sized pistons? help, noob at building motors.

i also i have a stock ls block. what should i do....

 

over sized pistons if you go stock might lose compression

 

I had some .02 overbored pistons/rods at 9.5:1 for sale not too long ago. You need to get the oversized pistons for that bore size. Too much of the rings will be exposed if you just run standard sized pistons.

 

You should be able to get the proper oversized pistons and rings at any Acura dealer's parts counter.
