.50 over Recon

The primary purpose of the slight overbore, .050, is to clean up the cylinder wall and provide a good seating surface for the new oversize rings.
While your displacement will increase marginally, along with your compression ratio, the main purpose of a .050 overbore is "rebuild," not performance; a worn cylinder wall is its only practical justification.
