hey guys i need your help, my friend just gave me a set of KB pistons that he was going to use on his 350 but sold them to me for $40 bucks brand new!! (he's going with a 454). Anyways on the side of the box it says KB 142+.040 and he said they were dished top pistons. Now i wanted to know what the "cc" for the pistons were. I heard -18cc, -15.5cc and some others. Now what is the right cc for these pistons?? i appreciate the info and i'll keep you posted if i hear anything, thanks...

 

look in KBs catalog or measure them yourself

 

i dont have a KB catalog or else i would know and i dont have anything to measure them with...

Of course the +.040" means you have to bore your block .040 over to use them.
