The Super 402 Flathead
BLOCK: The Super 404 uses a five main bearing Windsor block with a standard 4” bore and a 4” stroker crank to give 402 c.i. displacement.
DECK PLATE adapter makes the conversion to a Flathead. The 1 ½” plate is cast and CNC machined, attached to the block and has integral ports, valve seats, and guides. The valves run directly on the lifters, just like the original flathead. The over-bored and sleeved block makes a joint-less standard size cylinder. Studs from the deck plate hold the heads down.
CAM SHAFT by Crane, is a custom billet grind to fit the Windsor block, the standard Flathead layout and accommodates the roller lifters.
LIFTERS are OEM Hydraulic roller type to make valve operation quiet and efficient. No adjustment is necessary. Slight modification allows them to contact directly on the large valves.
VALVES and PORTS are much larger than original to supply adequate airflow to the 50 cube cylinders. Intake valves are 2” and exhausts
are 1 5/8”.
HEADS are designed with several objectives. Good water-flow from the Windsor block and a raised combustion chamber to accept pop-up pistons for high compression. The combustion chamber is iron to assure heat is transformed to crankshaft energy. The finned aluminum covers also direct the water to keep the spark plugs cool.
RODS are custom made steel billet to position the high compression pistons correctly in the raised deck cylinders. Cranking compression can be as high as 180 lbs.
INDUCTION timing is computer controlled with a knock sensor to retard spark in the event of detonation. This allows the engine to have a high compression for power and mileage. Distributor is mounted on the front of the engine.
COMPUTER controls fuel injection, ignition, and air fuel ratio. An OEM OBD 1 #7730 computer is reprogrammed to match the needs of the 402 FLATHEAD.
WATER PUMPS sit in shrouded housings, to increase the water flow beyond original when they ran in an open chamber. The water pumps are original truck style with modern seals to allow high pressures and RPM without leaking.
FRONT COVER serves as a timing chain cover, distributor mount and water pump mounts. It directs the water from the pumps to the original Windsor block water inlets.
EXHAUST from the center ports is routed through the valve lifter valley to join the end ports to exit on the sides of the block.
AUTOMATIC OR STANDARD Ford transmissions are easily bolted right up to the 351 Windsor Block to complete the power train assembly.
O.E.M. PARTS are used wherever possible: Block, bearings, pistons and rings, oil pump, crankshaft, timing gears and chain, vibration dampener, flywheel, oil pan and gaskets etc.
FINALLY an original looking, original size and shape engine makes the Super 402 a practical contemporary version of the popular Ford Flathead. It has been improved by using modern parts and materials to make it an excellent performing, reliable power plant for your Hot Rod or Machine.
