Here we have an original Aluminum (Shelby Style) Ford over the counter performance intake for a 351 Windsor. This Ford dual plane intake manifold was offered over the counter by Ford for cars like the Mustang Mach 1, Grande, Torino GT , Ranchero, Falcon, Fairlanes. Cars such as these would not want to use the other performance intakes labeled 'Cobra' and 'Shelby', so this was Ford's engineers alternative to get the job done. Identical in design to its counter part Cobra intake which was engineered as a racing product by Ford's designers. This unit was instant horsepower and easily bolted on, when properly mated with a 4 barrel carburetor and offered a successful upgrade. Our inspection revealed no welds or breaks and it has seen moderate use with the ports in good shape with NO rot thru abuse. This would be acceptable upgrade for someone who is trying to keep their car stock and at the same time enjoy better performance.The C90X number designated the 1969 Ford Over the Counter Racing program. With the decline of the Shelby program, Ford moved into a different era in pushing their own products, and intakes like this were the result. Offering the same exact design with different stamping, yet cast 'Buddy Bar' as the 302 version and the like. Great design, these quality products are Ford Tested and Engineered, this is a sure winner for those trying to step their car up a notch and at the same time retain value -Don't miss the chance to buy one of these rare factory pieces which was offered for only 2 years before being put aside as the 351 Windsor motor package was put out to pasture being replaced by the another option the 351 Cleveland which carried on as the racers choice.
