I am wondering if anyone on here knows what the stock bore is for a 1987 302. I am looking at a 1987 302 out of a GT and the owner is telling me that it is all stock butthe cylinder boresmic out to 4.020. Thanks for any help.

 

4.00"

 

ALL windsors have a 4.00" bore.

 

its been bored .020 over, i thought the norm was .030 over. its alright was long as you dont go past .040 over.

 

if ya wanna get technical its actually 4.0004-4.0048in
