Brie,
Google/Bing 'ford y block' and you'll get a ton of links. This one FORD Y is on top for a reason. Sounds like maybe if you just pull the 292 and take it to a good engine shop to be cleaned out good and then built back right you'll have what you want. Personally I like Scot - Sehr Performance Machine Engine Rebuilding Specialists You might give them a call and chat a bit about what you've got and what you want, but I'll warn you that you might end up shipping your engine north if you do.....
