I am not arguing that Biral was not used because I wasn't around at the time. But all of the factory documentation that I have come across stated the use of either of these two types.


Also, Nickasils were introduced in 1971 which would put the use of them close to when the ST's were being actively raced.

Aaron,

Do you have this type of document for the other ST motors we are discussing ??

If so, can you post them...

Does anyone know what type of work the factory may have done on these cases ??

TIA
