What bore ?? I have guys bring in 454 for a 496 build and not have it pass a sonic test and on any of those blocks it was one cylinder that failed the test.
I check every block cause I don't need the practice of doing the job twice because of a split cylinder or poor ring seal.
I have seen a few guys in my small area have build another engine out of there own pocket ecause they did not pay attention to detail.
You have to remember your dealing with OEM blocks that made how much power when stock ?
