After buying my 69 Z that was just rebuilt ( apparently by an idiot ) I found out that all I really have is a good standard bore 350 block and a new cam. I am thinking about building a 383 but looking at all of the choices I'm confused. Forged, cast, flat top, domed, Eagle, Scat I'm not sure where to start. The one thing I know is that I'm working with the original 69 DZ 302 heads the block is the same casting as a 69 DZ casting and I want a good street performance engine. Any help would be appreciated.
