I have a 1969 DZ 302 crank I was going to put in my 1967 Chevy II. But as time changes so do plans. Since everybody and there brother are making tube front ends for eariler Chevy IIs now. It opens up the door for a big block. How much is a part # 1178 DZ 302 crank worth? It is polished .001 under. I also have aluminum BRC rods that were with it when I bought it.
