A bit off topic, I know, but I found a '71 240Z that still had the SU carbs on it at a local U-Pull It type of salvage yard a few months ago. When you sign, in the fellow at the counter hands you a price sheet. Prices are given for parts, without regard to manufacturer, age, or condition. The price for a single barrel carb? Twenty bux.
