SBC Engine Identification (again)

[39chevy]

Can someone help me identify this engine code - K0930PHA?
The date code is H234 and the casting number is 14093638.

I know from the numbers that this block was cast 9/30/1994 in Ontario, is a 350 2-bolt made from 87-95, has a one-piece rear seal and flat tappets (although I've got all the stuff to use roller tappets).

What I can't find is what PHA means.

Thanks,
Don

It is a suffix code, should tell what it was installed in. My book doesn't show it.
