Google is a PITA for a question like this. Go over to ls1truck.com, performancetrucks.net, and fullsizechevy.com and ask. I don't know if you saw my original post, but the engine problems might be intake gaskets, fuel pressure regulator, water pump gaskets, and knock sensors. All easy fixes. Do maintenance on the trans, add a Corvette servo, cooler and temp gauge and it should last a while too.
