Hi Guys,
I am new to this forum, so bare with me.
I have an old 1970 something ute, which has seen better days.
I am planning to start the restoration in December or Jan and want to plan it out first.

Currently it has the A15 motor which we swapped out a few years back with the 4 speed box.

I still have the 120y block, and reading through this forum and others alike, I have found that the A15 head is a straight swap.
Now some years back I had a 120y sedan which I had a A14 motor modified, I think I still have the high compression pistons with conrods somewhere, I know I have the side drafts (Webber and Delorto;s,) need to look for the intake manifold.

Question I have is which parts from the A14 are interchangeable with the A12 motor, was it just the bore and stroke from the block which differed, if this is all Then my understanding is that I can change the crank to the A14 and keep the same stroke, change the bore to a A14, then put the A15 head on with the side drafts.
Any help would be appreciated. Thanks.

So you intend to bore and stroke the A12? Sounds like a plan. There are some details in the tech library but the general issues from my understanding are crank counterweight modifications and modifications to the small end of the conrods to accept the larger 19mm wrist pin of the A14 pistons.

Here is a useful link.

Unfamilia I don't need to change the engine No. using the same block at the licensing department and get police clearance on the engine. Its a few days event. which I don't need.
