Hey Cal and 427
I remember hearing that story about the building being 350 ft. away now that you mention it, however I was refereing to the rated horsepower of the Competetion Engines not street engines. The GT-350 race cars or 'R' cars as they have become known as, were raced with a 715cfm Holley carb on an Aluminum Hi-Rise Manifold. The advertised rated power of that engine was 350 hp with race heads, matched intake manifold and race cam and headers. And you could buy them complete from Shelby for racing.
The GT-350 street models utilized the 715 cfm Holley carb. and the Hi-rise mainfold with the TRI-Y tubular headers as did the 'R' cars but all bolted to the 271 HP 289 Hi Po. or 'K' code engine and developed and advertised increase of 35HP over the stock Hi Po. 289 to 306 Hp. The 289 Cobras came stock with HiPo 289 with the Ford cast iron intake minifold and an Autolite Carb., although there was a 2 4 barrel AFB's Manifold, (DRAGONSNAKE) and a Weber set up as options, and other's they would gladly bolt on for you at Hi Performance Motors for an extra charge of course! Some 289's sold new and used in '65 at Hi Performance Motors could get the 715 Holley Hi-rise as an option.

By the way, are there any purist out there interested in a pair of CORRECT &ORIGINAL Iron Race Heads from Valley Head for thier vintage racer? They are unassemebled and have been in storage since 1970 when they had one SCCA National Race weekend on them after purchased new.

Remember "Too much is just right".
