That is my point. Pontiac made fantastic racing cams. That same cam sitting in Wrong Island traffic gets old fast. You have to make up your mind what you want to do. Go cruising or racing. Hard to do both these days with speed cameras everywhere.
On the other hand, those two barrel 350 heads are probably small valve, low compression jobs. If you are really honest about what you are going to do, getting those heads done up would go a long way to making that 350HO street-able. Maybe just grind off the head codes, claim they rusted away, who would know? Choose a nice street cam, with a bit of grumble, and enjoy the hell out of it. Post the crummy 350 codes if you don't mind. [wink wink- nod nod]
