Swapping an LSx in place of a conventional small block isn't terribly difficult, but does require some adaptation. Corvette Fever magazine is doing a project that includes installing a 5.3 LSx engine in an '87 Corvette, so that should shed some light on what it takes to do a quality conversion.
I think it would be a kick to run an old-style small block, or any other engine for that matter, with an LSx PCM. I think that will really show off the capabilities of EFILive. I've been talking with a few people about doing a project like that. If it happens, I'll post the results.
