Need advice on where in So. Cali. to find an LA360/TF to swap into my 65 273 Valiant

Are you looking for a turn key motor and trans (freshly rebuilt)? Or are you looking for a motor and trans that you want to have rebuilt?
Looking for a decent running engine/trans to do the swap. I'll add headers, and a 4bbl. intake for now and later on probably do a build.
