I know some of you blokes will be able to sort this out. has me stumped from what i have read.

With my 1000 Wags i bought came 3 A10s. 1 is differnt. It has a late A12 style block. Dizzy in the middle, fuel pump at the front, Rear crank breather, emmisions head(big thermo housing, round port). It has a A12 fuel pump on it and a 1000 metal fan

The engine number is A10 313598

anybody have any idea?

Heres a crappy pic, can get a better one

I think they ran A10's in the E10 or F10 front wheel drive cars.

That clutch looks bigger then 160mm too

Keep rubbing....... might be an A12 restamped for rego

Just looks like a late A-10-12 block does it have the emissions tap on the right side of the enigne between the front of the engine and the first exhaust port ?

The distributor in that position indicates a 1974-or-newer engine.

Which Datsuns came with an A10 after 1973? There you will find the answer.

Look at the front of the engines & compare the distance between the top of the timing case & the top of the block, [head gasket face] & compare with the 'regular' A10's
If this one has a bigger gap, then it has a longer stroke & would therefore be a re-stamped fraud.

Yeah good idea dodgeman but hey are saying people would do something as terrible as that tut! tut! tut!

What about the A10 engine in the 1976 Datsun 100A (E10 Cherry)? Would that have the new-style block?

Looks like a 1000 flywheel though.. the rear face is as tall ts the ringear... ???

Well i think i solved the mystery!

It has a bigger gap from top of timing case to the deck of the block then the other A10s.

Plus where would i get a motor out of a Cherry in WA? I know of 2!
