Bigport Pistons To 4Agze Crank

[ae95- wagon kid]

I have a bit of a technical question

 

how would i go using the early 18mm bigport 4age pistons

 

and using the 4agze rods

 

in a 4afe block

 

i have done some measurements

 

but just want to put the idea out there to see if there is anybody who would see some flaws or possible technical hurdles.

GZE rods are 20mm, you can't use early pistons on them, you will have to also measure the crank to see if it is a 40 or 42 bigend unless someone else knows.

That is what I am referring to, the GZE will be 42mm.

 

Did a search on the 4af and there is a post saying that they are 18mm but I would have thought they were 20/42 being a later engine.
