Default .030 over 390
just a question....found the build sheet for my engine and said its .030 over. what does that mean for the ci size of my engine? not a lot of other info for internals. its a 390. is it a 427 or a 428 now? forgive me for my questions but just trying to learn about my car and you guys have forgotten more than i will know about cobras!
