At some point during Australian production the casting "CF" at the top of the rear of the block, next to the oil pressure sensor outlet was changed to "GF". Also at some point late during production in an attempt to reduce the clevelands tendency to overheat, a "pillow" block was produced to increase water capacity arround the cylinders. | At some point during Australian production the casting "CF" at the top of the rear of the block, next to the oil pressure sensor outlet was changed to "GF".

A "Nascar" block was produced by Ford Australia (exact year unknown) for the US market. Exact number shipped to the USA is unknown. These "Nascar" blocks were to have thicker cylinder walls and "better grade" cast iron, but due to bad core shift were no better than standard blocks. It is known however that most of these blocks were returned to Australia. These blocks were then used in regular production back in Australia. | A "Nascar" block was produced by Ford Australia (exact year unknown) for the US market.

| + | Intake manifolds and Carburettors: | ||
| + | Australian built clevelands used either a Cast Iron 2bbl or 4bbl manifold in 2v size ports. Initially 302C's were only available with the 2bbl (1974-1976) and 351C's had either a 2bbl or 4bbl option. | ||
| + | |||
| + | Rochester carby's were used on the 2bbls with an aluminium adaptor plate. Carter Thermoquads were used on 4bbl spread bore type manifolds with an aluminium EGR plate. Early production 4bbl manifolds had large secondary inlet ports. Later production 4bbl manifolds had the secondary ports reduced in size in an effort to increase mileage and throttle responce particularly on 302's with the 4bbl option. | ||
| + | |||
| + | To confuse matters Australian production 351C motors were mixed with US built clevelands (mostly 4bbl Autolite motors) through to about 1976 . Then it appears that US built blocks bought by Ford Australia were used up to the late 70's in regular production. | ||
