You already put 2 of mine up here, so I'll bite...here's 3 more of mine...in my old '31 C-dan, my '37 Chevy and '65 Stevens drag boat... What else is there, but a Nailhead!! haha
In my '57... In my International... one day I'll get to finish it. Waiting in the wings... An old 364... and some I've saved...
Back in the late 50s I was a Buick line mechanic. We were always told the nailhead was the one engine the the engineers said would never run. Its different, it looks like no other, it sounds like no other, It not a high reving engine, but it has guts, and stays together. Ice man
