Chevy/Olds aluminum block

[Seattle Sam]

"The KB600 Oldsmobile block uses big block Chevrolet internal components, which are available through Keith Black Racing Engines. Cylinder heads and manifolds are available through General Motors. The blocks are cast from the same 356 T-6 virgin aluminum that all KB Blocks share, (except for the Stage 15 fuel block) to ensure only the highest quality material. A multi-pattern bell housing pattern is machined into the rear of the block for use with GM or Chrysler transmissions. The big block Chevrolet or Oldsmobile head bolt pattern can be machined in the block.

Standard deck height is 9.800; available up to 10.200

Bore sizes from
4.250 to 4.500

KB600 can be made to accommodate up to 5 inch stroke crankshaft"
