Decking vintage engines

P.J. · #1 03-20-2005, 05:38 AM

The machine for milling the block can be a bridge port or a horizontal milling machine. The tool that leaves the machineing marks on the block is a carbide fly cutter. that is a tool about 8 inches or larger in dia which serated to accept carbide inserts
that can be replaced as they dull. The carbide tips can be secured in the tool with a set screw. Then when the tool gets to the end of the scribed line the machine travell is then cross
fed to avoid the vin stamp.
hope that helps

For a street driven engine, decking probably isn't needed unless the block is badly distorted. Perhaps I've just been lucky.

I agree with that thinking. Resurface heads and clean the deck of the block good. Use quality head gaskets and you shouldn't have a problem. I would be terrified the machinist would slip and remove the vin stamp and letter code. Not worth the risk!

Have the deck surface checked regardless of whether you decide to cut it or not. Many BBCs I've come across have needed 0.015-0.020 cut to square them up.

Good advice!
