This week, we've stretched the definition of muscle car just a bit and bring you a 1974 De Tomaso Pantera GTS.  The muscle car connection is this car's 351 cubic inch Cleveland V8 that looks over the driver's shoulder as you row through the ZF gear box.  Power comes from Ford, wrapped in Italian styling.  We know it is not a muscle car but we think it is very cool and worth sharing.  From The Brothers Collection.

Back in 1964, Super Stock drag racing racing was one of the hottest things going, and people loved the competition and energy of stock-appearing cars going much faster than normal.    The next evolution was Factory Experimental, a class that allowed manufacturers to get a little crazier with performance parts and special pieces in cars that still appeared similar to what was for sale in local showrooms.   This 1964 Mercury Comet is an A/FX car, one of 21 built, and it still retains all the "experimental" speed parts that it wore back in '64, like the 425 HP high-riser 427 and all the fiberglass body panels.     

http://www.musclecaroftheweek.com - This week, we're taking a spin in a very cool 1969 Mercury Cougar, one loaded with the XR7 option and the top-cat 428 Cobra Jet Ram Air V8!    Add to that the convertible top, and you have about the baddest Cougar you could buy in '69.    From the Brothers Collection.

This is one of the more unusual cars in the Brothers Collection, a Lime Gold 1967 Ford LTD XL featuring a factory installed 425 HP R-Code 427 and 4-speed manual transmission.    There were only a handful of these cars ordered in this configuration, and we share the details in this video shot at the 2014 Muscle Car and Corvette Nationals in Chicago.

The Mach 1 handling and appearance package made for some good looking and comfortable Mustangs back in 1969, but the heat turned up when you ordered a 428 Cobra Jet with the 3.91 or 4.30:1 rear gear.    The rear gear kicked off a handful of upgrades to form the Super Cobra Jet, a car that was intended to be a drag strip terror right off the showroom floor.    This '69 Mach 1 428 SCJ 4-speed car is a beautiful Acapulco Blue version from the Brothers Collection.
