1969 Mustang Engine Information – 302 cubic inch V-8 (4.9 L Windsor V8 + & Boss V8)

The 302 Windsor V8 + A Big Welcome To The Boss 302

The 302 cubic inch engine was introduced in 1968 to the Mustang and continued to be offered in 1969. The now revised 302 cu in (4.9 L) Windsor engine had 210 hp. In addition, a number variety of performance packages were introduced that included names like the Mach 1, the Boss 302 and the Boss 429. The two Boss models were to homologate the engines for racing.

After a very disappointing 1968 racing season Ford designed a new engine specifically for F.I.A. Trans Am competition in 1969, the Boss 302. The engine was introduced on April 17, 1969. About 8,600 Boss 302 engines were built. The Boss 302 block was essentially the next generation of 289 High Performance hardware, but features a forged steel crankshaft, 4-bolt main caps, and screw-in freeze plugs. These modifications were developed as part of the 302 Tunnel Port design. Street versions used connecting rods similar to the 289 Hi-Po while the Trans Am version used heavier 7/16″ bolts.
