Where to find a 360LA Roller

Mopar 92 , I am thinking that the core buyers are sucking up the 5.9 L engines . Much the same way they are buying the 5.7L . My local yard has 2 (5.7) and he wants $1500 each . He can keep them . Keep looking . Usually salvage yards have people waiting for engine cores to come in and often the high demand stuff goes out the same day .
