Not Ranked
With a 4.250" stroke, the standard 4.125" bore gets you 454 cubes. A 4.155" bore gets you 460.
You don't have to jump all the way to 468 ci....the hp difference between 454ci and 468ci would be nominal at best. If you started with the 4.125" x 4.250" combination, you could potentially have many, many rebuilds before any "major" work needed done.
