The Chris-Craft engine was oufitted with a Paragon 2:1 reduction transmission, a gear driven camshaft and a large capacity cast iron oil pan.

Certainly not the lightest engine package to power our boat, so we tore the engine down and replaced most of the parts with beefier and lighter performance parts. 

The engine was hot-tanked, magnafluxed to check for cracks and bored out .060". Brass freeze plugs, block petcock drain valves and a set of flat top pistons were also installed.  The crankshaft, rods and cylinder heads were also reconditionned. (18-JUN-2004)

The engine mounts, brackets and pulleys were sandblasted, primed with DuPont 2580CR urethane primer and topcoated with DuPont Imron urethane enamel. (22-JUN-2004)

Power upgrades include a mild marine hydraulic camshaft and lifter kit, a Crane Powermax H-266-2.
Cam specs are as follows :
- Advertised duration (Intake/Exhaust) : 266/272 degrees
- Duration at .050" lift (Intake/Exhaust) : 210/266 degrees
- Valve lift : .440"/.454"
- Lobe centerline : 112 degrees

The original Carter 3660 four barrel carburetor was rebuilt.  To save weight and increase performance, the stock cast iron intake manifold was replaced with a much lighter and better flowing Edelbrock Performer intake manifold.

The compact Velvet Drive bellhousing requires the installation of a 12-3/4" 153 tooth flywheel and a marine starter to match the smaller diameter flywheel.  The original Chris-Craft motor mounts were retained. (24-JUL-2004)

The engine was installed in the fullsize mockup.  Motor mounts were fabricated, the wiring system was completed and an automotive cooling system was hooked up so we could fire up the engine.  The intent is to break in the motor before it's installed in the finished boat.  A cam driven water pump and marine exhaust will be swapped in at a later date.
