Do a search and see what you can learn from that. I will say that the only significant problem is exhaust. You'll find that most achived messages focus on exhaust.

It all depends on how much you want to do with it. As a daily driver it can be a very simple bolt-in with cast iron exhaust manifolds. Building a 500+ hp engine needs more than just an engine swap.

There are a couple of clearance issues depending on what you use. Things like wiper motors getting in the way of tall valve covers etc.

As everyone else has mentioned so far, do a search in the archive. There has to be at least 100 messages dealing with big block swaps already. We don't like answering the same questions over and over.
