DD...would you know of any other gearbox that has interchangeable parts with FS5W60A?

DD....Here are some pics. This is the 990 round port closed chamber head? Front stamp shows 416. Can you tell me anything more about this A14 motor? I could not locate the engine stamp on the block compared to where my A15 is stamped.

Hi DD. The downdraft intake I have came from a H89 head. Oval intake matched the oval ports.

Also when you get a chance please respond to question I had on the 990 head. I posted it in the Photo Album section.

I have a FS5W60A 5 speed with worn main drive and counter gears. Are these 2 gears interchangeable with the 60 series 4 speed?

Appreciate the info DD. So in 1974, the A13 was introduced and later years with the A14 and A15. This particular engine is an early A12, dizzy below #1 plug. What years and what vehicles came with the late A12 engine? I am familiar with the A12A that was offered in the 210 beginning in 1978.

Thanks DD. So then this would be an open chamber meaning lower compression? And does it have round or oval ports? I have seen the GX heads with the "Japan Nissan" stamp. Some GX heads do not have this writing?

Buddy of mine picked up a 1973 1200 car. He says it has original early A12 engine with 4 speed. Plans to pull both engine and gearbox out and no use for it. Cylinder head has no markings. Any idea if this is open or closed chamber, round or oval ports? Can't tell if it has double valve springs from pictures. He said manufacture date is mid 1973.
