CHOATE Engineering Performance Crate Engine Features:
Full CNC blue print machining.
This means boring, decking, honing and line honing to the designers intent.
Align honing the main bore housing allows the crankshaft to center in its housing as well as providing the necessary finish for heat dissipation of the bearings.
Afterwards, the block is fixtured in our Rottler CNC vertical machining center. This is to insure the cylinders are at ninety degrees from the crankshaft centerline. After this, it is moved into our Rottler CNC honing center where the cylinder wall diameter is machined to .0002 inch consistency. And the piston to wall clearance is determined per the application, and honed to size.
Once the foundation has been made true, the deck suface of the block is then machined to a surface finish of 30Ra or better. This meets or exceeds the factory specification for both flatness and smoothness of the block to head sealing surface. This is mandatory for proper sealing of a MLS Gasket.
Optional Parts are not installed and are covered under the manufacturer’s warranty, not by CHOATE.
