    We're trying to do some research on the KB Olds block.

    What is the difference between the KB500 and the KB600?

    Can you get them with 7/16" head studs? Maybe they need to be 1/2" threads on the block side and stepped down to 7?16"?

    Does anyone run bigger than 4.500 bore in these blocks?

    The KB500 is a technologically advanced aluminum version of the Big Block Chevrolet engine. The KB500 can be used in a variety of street or racing applications, such as boat racing, Pro Stock or any of the “Pro” bracket racing classes. A 540 cubic inch version of the KB500 was the motivation behind Hot Rod magazine’s Keith Black Camaro project car, which illustrated the true versatility of the KB500. The block will accept all factory and aftermarket parts common to the Chevrolet Generation IV 454 block. The KB500 block package includes: fully machined block with race-ready removable sleeves, main caps, installed cam bearings, special aluminum screw-in core plugs, installed front cover and head dowels, head stud kit (of your choice) and all necessary hardware.

    Choose from Chevrolet, Brodix, Dart or Pontiac style head bolt patterns

    Standard deck or +.400 tall deck

    Bore sizes from
    4.250 to 4.500

    Clearanced for 4.250 stroke cranks, but will accommodate up to 4.750 stroke cranks.
    (with steel rods)

    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

    I had read all that on there website but did not really understand the difference. Is the 600 solid and the 500 water?

    The 600 is the kb olds blower block. They make solid and water and have massive crossbolted mains like a hemi.Oddball oil pan, geardrive and starter.
    New century makes a clone that i'd recommend. We've had horrifying exp with KB.

    It's a decent product but don't ever let them work on it.
