Hey mate, use the GX dizzy with the A14 bottom plate, that way you have the correct advance curve for you GX Su's.

Exhaust manifold should fit no worries, head does interchange but you have to do something to get the oil to the top of the head, not sure exactly what, do a search, plenty of discussion on that.

EDIT: I think you actually have to fill the oil hole to use the early head on the later block, its the 74+ heads that have a different bolt to get oil up to the top of the head. Someone will know more.

Hi Guys

I am thinking of upgrading my engine in the future. As you all know, I have the A12GX engine. I am planning on getting a A14 block with the 5 speed which should give me with my h145 diff about 3500rpm at 120km/h.
I want to make the A14 as close as possible to GX. I want to fit the GX cylinder head, GX exhaust manifold which will be cleaned up and powercoated, GX cam and GX distributor.

My questions:
1. I have fitted a pertronix ignitor kit for the distributor. Either I want to fit the complete GX distributor or fit it into the A14's distributor.
Is the points being used the same for A12 and A14 engines? Why I am asking, is I just want to know if the ignitor system will work on the A14 distributor.
2. When using the GX exhaust manifold, will it fit or is the A14 engine taller giving a possibility that something might be in the way or even the exhaust manifold being too small to flow a 1400cc.
3. Can I straight fit the cylinder head or is there something I must drill. A oil hole or something.

Any info appreciated
