Are you sure it would not be easier to upgrade to a 3.4 block and crank? It is a lot more ridget setup. There is not a lot of aftermarket parts any of GMs 60 deg V6's. Atleast not for the ones made in the 80's and early 90's. Most people just upgrade to a V8. High volume= cheap, Low volume= costs a arm and a leg.
