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

In that case, this combo sounds like a decent candidate... (Not mine)

360 Dodge engine/ Torqueflite transmission
Yeah, I saw that on craigslist. Also thought I'd look for a running car,truck, or van with that combo. A few months ago I ran across a half dozen "Drivers" for under 800.00 but haven't seen anything like that in a while. Might go ahead and put a TF behind the 273 so at least I can get the 8.75 rear in, frames tied, mini tubs, etc.
