Kind of expensive but how bad do you want it? I purchased one recently for far less but had to look for a while, how patient are you?

The 3991399 casting was used for all 71-E72 CORVETTE small blocks, LT-1 and base engine. It was also used for some MD/HD trucks with small block during this period. It was not used for any other application.
