CNC Engine Block Machining

We've endeavored to have our machine work carried out on the finest, most accurate equipment available.  As of March 2007, all of our engine block work is carried out to the extremes of perfection on a CNC engine machining center.  Totally computer controlled, and programable, this specialized equipment eliminates inaccuraties and errors that can be introduced with manual equipment.  Because this CNC engine center also bundles multiple machining operations into one piece of equipment, we no longer have to worry about different individual machines introducing any deviations in tolerances between machining steps.   If you're a British car owner that seeks perfection, you will not find another engine rebuilder that is able to produce as fine of finished unit.  The CNC block machining center is a major contributor to the high level of quality and performance on our engines.

Wishbone Classics is able to perform certain machining operations on your engine that you cannot have done elsewhere.  We're able to bore Triumph blocks to accept cam bearings, we've even produced specialized tooling to shorten the duration of this procedure - which saves you money, because we can do it quicker.  Need oversized lifter / tappet bores?  No problem.  Need someone to fit steel main caps to your block and line bore for the proper fit?  No problem.  Can't find a shop that offers a crankshaft nitriding service?  Well we offer that as well.
