Re: Preparing for the worst...
Your 97 block is a Gen 1 block with a one piece rear main oil seal so any Gen 1 350 block with a one piece rear main will work.
I am not sure if the Vortec used a Roller Cam or not; however, the one piece Rear main blocks can be machined (drill and tap some bolt holes) to support a roller cam.
