Now ive been doing alot of research and have found out that after you bore the block the combusion chamber needs to be bored as well... In doing so you are lowering the CR... If you have set CR on your pistons to hold that CR you would have to get pistons with Higher CR to retain the CR you truly want... If anyone knows anything about this please help me out because im soo confused....

that depends on how big of bored your talking.

if its just oversized .25-.50, then dont worry about it.

 

im trying to do 86mm

 

then you may need to modify the CC, but I have no further info on this process.
