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.
