Hi Jim,
Great minds think alike
. In the early 1990's, I was hitting all the junkyards in Lindenhurst near Hoffmann Avenue with no luck. During that time, those junkyards had big blocks, muncies and 12 bolts laying in racks. I actually had found an Amity Chevrolet emblem during one of my searches. That dealership had some very knowledgable people at the parts counter. I bought my LS-6 from them in 1988 and it's still in my Chevelle
