318 to 360- what is interchangeable, and what do I look for in a street motor?

With the help of a friend, I have just determined that I have a bad thrust bearing in my 318. Since I have to take the engine out anyway I'm seriously considering using this problem as an excuse to move up to a 360. But of course, I am fairly strapped on cash, so we'll see if this is truly viable.

Keeping in mind the issue- a bad thrust bearing- what is the minimum that I need to replace to swap to a 360? Can I get away with an assembled short block and use my 318 heads, intake, carb? Can I use my stock exhaust manifolds? How about engine mounts, starter, flex plate, flywheel? The transmission is the same right?

Meanwhile I'll be keeping an eye out for a 360 here and on craigslist. Just looking for a reliable engine, doesn't have to be freshly built, but it has to be something I can put in my car and drive across long island without worrying. Not looking for a strip oriented engine either, needs to be street friendly. So let me know what I should AVOID when looking for a 360 as well please!
