We have several NEW GM ROX 4.500" bore center bare blocks for the small block Chevrolet platform available for purchase.
All block castings are NOS GM components. The 4.500" bore center platform (standard SBC is 4.400" bore center) will allow the user to machine the blocks up to 4.250" bore while maintaining a minimum wall thickness of .225" on the thrust side (This platform has enabled 4.310" bore in the past). You can build the big bore short stroke combinations that have been so popular when high HP is a requirement!
Most blocks that we have in stock have already had the SB2.2 lifter pattern machined into them (we do have 1 block without lifter holes). The blocks are made of compacted graphite.
****WE DO HAVE 1 SINGLE 4.400" VERSION OF THE ABOVE BLOCK. IT IS A RARE PIECE....BUT WE HAVE IT!****
Crankshafts, camshafts, intakes, valley trays, belt drives, valve covers, etc....are also in stock.
Volume purchase discounts are a possibility...call for details if you are interested in multiple blocks.
Blocks Start from $1500 each
