does this sound right?

I just brought my 302 block out of an 88 mustang to the machine shop to get work done. I thought the block was stock but they told me it has been bored to 40 over. This is good in some ways but last race season it ran a 14.7 . It was completly stock other than it beein bored out and exhast. Does this sound right to any of you?

thanks dwp
