Part No: BTD-CUT-CHS
Correct dowel hole location in the deck surfaces of the block with this specially ground cutter and the Bor-Tru Kit.
With the installation of special I.D. drill bushings in the Bor-Tru Plate for small block Chevrolet and small block Chrysler, this cutter will precisely machine the dowel holes in the correct centerline to accept a replacement OE-size dowel.
Putting these holes in the proper relationship to the cylinder bores, corrected with the Bor-Tru, ensures proper combustion chamber alignment over the cylinder bores.
