1965 Mustang Engine Information – 260 cubic inch V8
This was the first V8 installed in the Mustang, its block was painted black (paint code 903), heads were blue (paint code 963), and the valve covers and air cleaner were light blue (paint code 958).
It was an enlarged version of the previous 221 CID V8 that Ford used in previous cars and the 260 had 164 horsepower. In 1962, it was used in the Shelby Cobra, the Mercury Comet and the Ford Fairlane. Then in 1963, it was used in the Shelby Cobra, the Mercury Comet, the Ford Fairlane, the Ford Galaxy, and the Mercury Meteor. In 1964, it again saw service in the Shelby Cobra, the Mercury Comet, the Ford Fairlane, and the Ford Falcon. Finally, the little v8 was installed in the newly introduced Mustang in April 1964 and was offered only until August.
The 260 was an overhead valve 90 Degree V8 engine and a good performer. It was easy to add modifications and make good horsepower. Carroll Shelby used the little 260 in his first Cobras and really kicked butt. The street version ran on regular leaded gasoline. Intake manifolds were cast in two variations, the street version which was cast iron and the Shelby performance version cast out of aluminum. The Shelby version also enjoyed solid lifters while the street version used hydraulic lifters.
Carburetion was achieved through one of the following carburetors: Autolite 2100 (2V)with an automatic choke or a Autolite 4100 (4V) using a manual choke.
The engines used a single point vacuum advance distributor for the standard engine. However the Shelby Cobra was equipped with a dual point mechanical advance distributor. However as Chevy tried to catch up with ford, they rumored to use a 283 CID engine and the little 260 was not enough engine to beat the 283 so Ford upped the game with the 289 starting with the late 1965 Mustang models.

Engine Torque Specifications
All torque specifications provided in this table are those recommended by FORD. If you use special bolts, follow the torque specifications provided by the manufacturer. I recommend that you use the 3 step torque technique where you torque down the bolts in three equal steps. Once you have reached the maximum recommended torque setting, go around one more time. Do not torque in a circular pattern. Always torque cross to cross.
