The first time I heard a nailhead run it didn't sound like mine did when we got it running yesterday. Wow. If it wasn't a buick, I wouldn't believe that there was a bone stock big block runner left to be had. How many chevys had big blocks in the first place. Anyway, siiting behind the wheel of a 63 wildcat is actually more satisfying than I had dreamt. I have had trouble describing the sound of the exhaust. Any input? you know, onomatopoeia
