individual intake valve passages for each cylinder and

Forced feed by oil pump driven directly

connecting these passages to an Intake manifold which

off camshaft, to all main, connecting

also has individualized passages for each cylinder.

rod and camshaft bearings as well as

tappets and timing gears.

This equal distribution results in maximum power,

smooth operation, easy starting and longer engine life.

9. Cooling

Coolant circulated by centrifugal pump

driven by 'V" belt from fan drive pulley.

Full pressure flow through engine at all times.

Engine capacity - 9 qts.

Engine and Radiator capacity - 9 qts.

10. Oil Pressure

Maximum - 30-40 p.s.i.

Minimum (Idling) - 7 p.s.i.

11. Oil Sump Capacity

Four quarts - add one-half quart extra when oil

filter is replaced. Throw-away cartridge type

filter.
