yes not quite but these happen to be 40 thou oversize pistons so maybe the standard size could work ill dig around a little bit more about these motors.....
yep found out it is at 80.9 mm and the pistons i have are 83mm wayyy to big

Couple of problems.
The stock bore of an A14/15 is 76mm & 79mm is generally regarded as the maximum overbore size.

The wrist pin hole in the shorter A12 rod is for the 17.5mm pin. The longer A14/15 rod pin hole was 19mm.

The A12A & short deck A13 used the shorter A12 length rod, but with the larger 19mm pin hole.

This does not look like a workable combination by the looks of it.

hey guys i got some pistons for a torana and am wondering wether they may fit into an a14/15 with some work
gudgeon pin sits down lower by around 5mm and is 19mm same as an a12 rod so if using the a12 rod in an a14/15 block lowers stroke by the same amount should work
the pistons are 81mm in diameter i am not sure what the bore of an a14/15 can be taken out to? so all this may work? oh and they are also flat tops
