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.   

The "K" in the 5th VIN position has special meaning to early Mustang fans, and this 1966 version is a perfect example of why! The K code cars featured not only the 271 HP 289 V8, they also rode on a performance suspension system. We take a look at a Signal Flare Red K-Code from the Brothers Collection to learn more.

This week, we move off the mark from the typical Muscle Car into the world of mid 1960's luxury sedans, only to find that this 1 of 3 ever built 1965 Ford Galaxie 500 LTD is sporting an 427 for power!    The high-compression, dual-quad side-oiler V8 is coupled to a 4-speed transmission and a 4.11:1 rear gear, making this car one of the most comfortable drag racers ever built!    This luxo-liner LTD is one of the many unique rides in the Brothers Collection.

This week, we're showcasing a Bright Gold Metallic 1970 Ford Mustang BOSS 302.   This is one of the high-revving "hybrid" engine cars which resulted from the homologation rules of Trans Am racing, which dictated the automakers needed to make a street version of the cars raced in Trans Am.   This meant the 302 cube V8 that was built from a Windsor block and topped with Cleveland heads needed to be readily available to the public.   Add to that the low-slung suspension, high-impact graphics, and other performance touches and you have a hot performer that was great fun to drive.   From the Brothers Collection.
