I've got a '99 Cobra block that's been bored .20 over. The machine shop is waiting to get some pistons from me to re-assemble the block. I'm just putting some stock '99 Cobra pistons back in it, but the Ford catalog doesn't list sizing like that. Here are my three choices for pistons:
Grade #1 (90.167/90.182 bore diameter)
Grade #2 (91.180/90.195 bore diameter)
Grade #3 (90.193/90.208 bore diameter)
Any idea which of those I should order for this block?
