This is a brand new Holley 1250 cfm gen III Dominator coated in Hard Core Gray. It's never had fuel in it - taken out of the box for pictures. This carb is about 2 years old and was purchased for a project that was never completed. I need to clear off the shelves and make room for a few other items, so my loss is your gain.

6061T6 BILLET ALUMINUM METERING BLOCKS- Improved durability, true gasket sealing (sealing surface integrity), bright dipped anodized for good looks and corrosion protection

Fiat chief exec Sergio Marchionne today warned of troubled waters ahead as Europe's car makers prepare for a radical restructuring. Marchionne, who's the current president of trade body ACEA, said factory closures were looming and repeated his call for a concerted EU-wide response to overcapacity. He warned that national interest was blocking action to strip out excess capacity, caused after European new car demand crashed by 3 million in the past five years.

What we have here, according to the seller, is an actual one-owner, 4,418-kilometer (2,739 miles) BMW M1, recently imported to the United States from Germany. That's right--the original BMW supercar, one of 456 reportedly built. While the 277-hp straight-six may not sound too impressive today, keep in mind that the European Ferrari 308 only made about 250 hp at the time.
