Most of the AA adapters are designed for the 4.3 and smallblock GM pattern, they even have a few with the BOP buick olds pontiac pattern. Not sure if they make much for the GM 60 degree pattern*. Engines with this pattern aren't really that popular to the engine swap crowd so aftermarket adapters are limited. Just check on that first before you keep going down this route.

*Engines with this pattern are the GM 2.8, 3.1, 3.4, 3.8s (except the Buick 3.8s) Caddillac 4.1, Northstar, Aurora and a few other v8 caddys.
