It is difficult to differentiate 351M from a 400 externally. The most accurate way is to remove the oil pan and look at the crank. | It is difficult to differentiate 351M from a 400 externally. The most accurate way is to remove the oil pan and look at the crank. | ||

| − | + | 351M/400 share the same transmission bolt pattern as the 429/460 (385 series)motors. One exception. The 400 was available with FMX in full size Fords in the early 70's and has the smaller bolt pattern. | |
| − | + | All 302C/351C blocks use the smaller 6 bolt transmission pattern, C4 or "Windsor" type etc.. 351C's were available with 4 bolt mains (HO or Boss). 2V heads and 4V heads were used depending on option. Originally 2V meant 2bbl carb. and 4V meant 4bbl carb. However it was soon discovered that the huge 4V ports were not much good for street applications. | |

| − | Blocks: | + | '''351C and 351M crankshafts''' are not interchangeable. They have the same stroke but journal diameters are different, 2.75" Vs 3.00". Connecting rods are not interchangeable between "M" & "C" motors, 6.58" Vs 5.78". |

| + | '''Australian Crankshafts''' are Cast and have a raised 302 or 351 I.D. cast into the crank. Australian 302's have a longer connecting rod @ 6.00" (351C @ 5.78") | ||

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.

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. | Australian built clevelands used either a Cast Iron 2bbl or 4bbl manifold in 2v size ports.

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. | Rochester carby's were used on the 2bbls with an aluminium adaptor plate.

| − | 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. | + | To confuse matters Australian production 351C motors were mixed with US built clevelands (mostly 4bbl Autolite motors) through to about 1976-77.
