The Windsor motor was modified to increase its power output when installed into the HO series falcon ( XWGTHO Phase 1 ) which was used in production car racing.
The motor was given a bigger 600cfm carby, Aluminium inlet manifold, hydraulic lifters, A different camshaft grind and heavy duty alternator.
The modified engines were only fitted to the HO seriers and had H stamped on the compliance plate as the engine type.
HO stands for handling option as these models did have some suspension upgrades but most of the modifications were made to the motor.
The Windsor motor was replaced by the Cleveland engine
during the March/April 1970 production and the first modified for racing Cleveland was fitted to the ( XWGTHO Phase 2 )
Look on the value covers, windsor has 6 bolts. The cleveland has 8 bolts.
The Windsor is a small block, basically an enlarged 289. The Cleveland is a big block, more high performance. You can tell the difference from the outside by looking at the valve cover. The Cleveland has 8 bolts securing it down * the Windsor has 5. Also the thermostat cover bolts to the block on a Cleveland and to the intake on a Windsor. Neil
