OK, see if you can make sense of this then...
The 313 has a stock bore of 3.88. The 318 has a bore of 3.91. The 301 has a bore of 3.91 as well. The 277 is 3.75.
To make a long story short...there are none that are 4" standard bore.
Mine has a 4.10 bore?
It would have to have been bored .200 over in order to even be a 318 which has the biggest bore of the "A" Poly engines which mine obviously is according to the P31 engine ID?
I'm stumped guys.
