Consider +0.020 Overbores Due to Diminishing Engine Supply

We appreciate your perspective and feedback. While the concerns regarding engine availability are well founded, this is not a can of
worms that the committee wants to open at this time. It is worth nothing that most platforms for this category have rebuild
tolerances in the service manual. Engines that meet the tolerances listed in a vehicle's factory service manual meet class rules and
philosophy.
