New! 364709 Gm Chevrolet 350 Nascar "mall" Chev Balancer Dampener Corvette Vette on 2040-parts.com

This is a new and unused 8 inch torsional/vibration dampener balancer, part number 364709, as originally shown in the GM (now Chevrolet) Performance catalog. These nodular iron dampeners marked with the "MALL" insignia were originally used in 350 Chev smallblock NASCAR motors because of their ability to withstand 8000 RPM with total reliability. The construction of these dampeners were balanced to racing specifications, and the elastomer ring used is a high-temp material - as advertised by GM. This balancer, as I understand it, is intended for internally balanced, post 1969 smallblock motors, those with a 10 degree advance timing mark (this as opposed to the 2 degree advance mark on pre-1969 motors). The nodular hub and outer ring of these units were balanced separately upon construction - then the fully assembled unit was again balanced as one component. This is a high-quality part at a very reasonable part, no doubt. This is Detroit, and I purchased this balancer a good number of years ago (like back in the 1990's), and it has been sitting on a shelf in storage all these years. This part has never been on a motor. The tiny amount of corrosion evident on the unit is shown in the photos. This unit is as-found following storage, with nothing having been done to it whatsoever. You get what is shown in the photos. No abrasive has been used to clean rust or damage off - thus possibly throwing off the factory balance (anything you do to these units is supposed to result in a re-balance, according to the original factory information). The plastic elastomer ring is also as-produced originally, with the same durometer feel to it. The balancer was stored in a sealed plastic freezer bag the entire time. Please note - all of my ebay sales are final. A little old lady caused me more aggravation because of this issue of customers changing their minds. What you see in the photos - you are guaranteed upon delivery - but now nothing more. The balancer is perfect, but when you purchase it - it becomes yours permanently. I don't sell junk, but I certainly do wish all you racers and fellow performance engine builders the best in both this season's activities, as well as in the future of motorsports. Thanks for your time, Rrrustyron |

Chevrolet is bringing CNG power to the Silverado HD
Mon, 10 Feb 2014Chevrolet is taking CNG-powered vehicles seriously, with so many of their trucks being used in commercial fleets, so it was perhaps no surprise that we'd see a version of the 2015 Silverado HD that can be run either on gasoline or compressed natural gas before long. Chevrolet brought the 2015 Silverado 2500 HD CNG to the Chicago Auto Show, to let prospective buyers as well as the media to learn about at the savings that could be realized with this environmentally friendly setup. The HD CNG truck will offer bi-fuel capability coupled with its 6.0-liter V8 engine that's been modified with hardened valves and valve seats to run on compressed natural gas.
2011 Audi R8 GT, an AW first look
Sun, 02 May 2010Three years after it burst onto the supercar scene, Audi has unveiled a hard-core version of its R8 called the GT. Based on the existing mid-engine R8 V10 and incorporating aerodynamic, weight-saving and mechanical developments used by the company's R8 LMS GT3 race car, Ingolstadt will build just 333 copies of the new 560-hp four-wheel-drive performance flagship. Pricing has not yet been revealed, but given the extent of the changes to the new two-seater, buyers should expect a hefty premium over the R8 V10's $147,000 price tag when the GT goes on sale in North America.
Citroen Lacoste concept car first pics
Mon, 20 Sep 2010This is the Citroen Lacoste concept, a playful tie-up between the quirky French marque and its equally French fashion partner. If you think you can find a hint of the next-gen C1 in here then good luck with that. After all, this car has no doors, no roof, an inflatable hood and a retractable rear bench which is literally that, ie, a bench.
