You can also get a 292...one of the larger inline 6's. I think you can still find them sometimes in salvage yards, as they were used until the 70's. Cost is going to entirely depend on what you find.

If you have to rebuild it, then it will probably cost a bit more than your typical V8. But I'll bet you can get it rebuilt for 3 to 4 grand, depending on your machinist.

You can rebuild a small block V8 for less, so your cheapest option might be to convert it to a V8. But that's a personal choice. You can rebuild a V8 for less than 2 grand if it's just a stock rebuild.
