Pros and Cons of putting a 327 back in my 68 Suburban

[Brewski*]

Hey Everyone,
Sorry I have not been around for a while I am very busy getting short-track skaters ready for the Olympics.
My 350 motor blew in my 68 burb. It originally came with a 327. I have not heard too may good storys about 327s but think that for restoration purposed I may go with a 327 from Hiperformer. They have a 350 with a 4 bolt main for not much more $$. I need some advise on the Pros and Cons of putting a 327 back in my 68 Suburban to Help me decide~! Let me know what you all think~!
