Important Information:

• Sizes in reference to Deck Height, Cylinder Bore, Wall Thickness, etc, listed in these instructions are Nominal. This Block must be professionally finish machined.
• Due to a vast difference of opinion among professional builders regarding specifications and procedures, all blocks, when purchased bare, are finished within factory +/- tolerances. Tighter than factory or OE specs when applicable.
• Cam bearing OD should be de-burred before installation.
  When initially removing main caps, the caps & block should be de-burred before reinstalling; this will insure that correct main size is maintained.
• This Block should be assembled by experienced, professional engine builders. Many parameters such as Cylinder Bores will need additional, professional machine work.
• Many pistons are oversized, and cylinder bore must be honed to correct skirt clearance. Very few aftermarket components are drop ins to any engine block, without additional checking/machining.
