Not around here! 318s are everywhere 360s are difficult to come buy and 340s are extremely rare and expensive! I was fortunate enough to get two 360 blocks this year for spares. But had they been 318s id still bought them!
That is weird, I am only a few hrs from you and basically any LA based mopar is hard to find.
340's yes few and far between, but I have enough for a while, 360's I know where there are quite a few I can buy cheap.
But a drop in running 318, I think they are all in the scrap yard, crushed by now.
