I have bought a 73 Mustang with a supposed 351 cleveland. It has a replacement motor built in Australia with the code JG71PL and then 56567K.
I have figured out that 'J' is Australianbuilt motor, and 'G' is the Broadmeadows plant. I also know that '71' is the model and 'PL' is the year and month. I just dont know where to find the codes to tell me what model, and figure out the year and month. I also do not know what the 56567K means. Can anyone help.
The date codes pl mean 1974 jan i cant find the model codes but in 1974 the model code for a utility (i think you guys call them trucks ) is 45371 ending in 71 and the engine code k is a 5.8 litre 2v high compression enginehope this helps

You can tell by looks or by the VIN number if the engine is original.
The fifth digit could be H or Q. H is for the Windsor engine and Q is for Cleveland. The Windsor looks like an ordinary 289 or 302 engine, the Cleveland is a big head 400 version. I don't think they used a 4bbl Windsor but they did use a 2bbl Cleveland so that is not a good example.
Everything will need to change eas far as engine, transmission, and most likely rear end.A 302(5.0) swap would make more sense because they came in these cars and there will possible be some factory brackets and other things availiable. When you say 351 i am assuming you mean windser. This engine is in the same family as the 302 but thats about all they share. It has not been in a mustang since 72 or 73 and those were much different cars. If i wanted a 5.0 stang i would just buy me one. this will be a very expensive project and there will be many unforseen problems.
Well there is a 302 cleveland, they are mainly an Australian engine. Identifying one is much like telling the difference between a 351 windsor and a 351 cleveland. Based on the fact that it's from Ford's 335 engine family. 8 cap screws to hold on the valve covers, the block is longer do to the timing chain housing being integrated. The fuel pump bolts are mounted vertically, and the exhaust bolt holes are diagonal. Also, a big difference between an american 302 and an aussie 302 cleveland, is the connecting rods for the cleveland are 6.000''. Where the american 302 connecting rod length is 5.090". Also, referring to a 302 as a windsor is incorrect, it's block families name is the 90 degree v8. The only engine in that family that is properly named the windsor, is the 351 windsor. The 90 degree family also includes the 302 boss. The boss has cleveland style heads, and the block has screw in freeze plugs.
