340 .040 Bore Okay?
What is the production cast number after the 340 on the block? The higher the number the more chance of the cylinder being off set. Usually 340-1's are the best and there seems to be little problems with blocks up to 340 -8. Here is a example of a Race X block they were all casted as 318's this one was terrible 318-11. So bad the one lifter bore was missing a piece when casted. so the had to be welded and bushed
