There were 2 302 engines sold in Australian by Ford both were from different engine families.
The 302 Australian (only made for the OZ market & also called a 302C ,C for Cleveland)
and the 302 Small Block
The Australian 302 is a 335 series family engine also known as the Cleveland's
The 335 Series engines consisted of the 302C, 351C, 351M and the 400.
The 400 has a 1/2" higher deck height to accommodate the 400's 1/2" longer stroke. The 351M (M for modified) also has the 1/2" higher deck as it is a 400 with the stroke shortened by a 1/2" The 400 and 351M also utilized the larger 385 Series engines (370, 429 ,460, 492) bell housing bolt pattern.
The 302C and the 351C use the small block bell housing pattern.
The more common 302 (AKA 5.0L) the one all us over here in NA know is a Small Block Ford engine.
The Small Block Ford engine family consists of the 221,255, 260, 289, 302, 302 Boss (a 302 with 351C type cylinder heads) and the 351W (W for Windsor). The 351W has a 1/2" higher deck to accommodate the 1/2" longer stroke in the Windsor.
The Small Block Ford's and 335 Series engines have the same bore spacing and head bolt pattern. Making swapping the better breathing canted valve heads from the 335 series on to the small block quite easy. This was the basis of the 302 Boss of Can Am racing fame.
The Small Block 302 is very frequently called a 302 Windsor this is incorrect labelling of the of the 302 Small Block Ford.
So Ryan I assume you are talking about a 302C that was swapped in the carrier and not a 302 since you mentioned it could also be a 351. And I do not think the 351W was ever sold in OZ in carburated form.
Dimentionally the Small Block Ford's (excepting the Windsor) are smaller than the Small Block Chev's (SBC's).
If you swap in a small block chev I would opt for an eariler 283 and avoid the later 302SBC as it is a pig of motor and shares little in common with the 302SBC of Can Am fame. You also have the option of using a 4.3L Chev V6
They are bullet proof cheap and easy to find and are basically a 350 Chev with 2 cylinders hacked off.
