MUSTANG Boss 302 Shaker Restored to Original Look
When the Boss 302 came out for 1969, Hot Rod magazine said it was "definitely the best-handling car Ford has ever built." Motor Trend called it "the word of our time...good, only better, fuller, rounder, and more intense." The street version of Ford's Trans Am racer was available to the public for less than $3,400-that's reasonable at only $800 more than a base six-cylinder Mustang coupe.
For that extra money, a '70 Boss 302 buyer received a G-code 302 with Cleveland heads, large canted valves, a forged-steel crankshaft and connecting rods, a high-rise aluminum intake manifold, a 780-cfm Holley carburetor, and a dual-point distributor that put out an advertised yet understated 290 hp. Two manual four-speeds were available: a wide-ratio box for the strip and close-ratio gearing for the road course.
The front suspension received 350-pound high-rate springs, heavy-duty shock absorbers, and a stabilizer bar. The Hotchkiss-type rear had 150-pound leaf springs and a staggered shock arrangement with a stabilizer bar. Front disc brakes were mandatory, and steering was a quick 16:1. Standard F60x15 tires were mounted on 15x7-inch wheels with flat "corporate" hubcaps, although many Boss 302s received the optional Magnum 500s. Space-saver spares, labeled 7.35, were standard issue.
Ford designer Larry Shinoda left his mark on the '70 Boss 302 body with its black-striped hood (paint in the center and tape stripes on the outside), chin spoiler, black tail lamp bezels and panel, color-keyed dual racing mirrors, and blacked-out decklid. Reflective "hockey stick" tape striping incorporated "Boss 302" callouts on the fenders. A Shaker hoodscoop, Sport Slats, and a rear wing were optional.
The Boss 302 engine is a racing small-block V8 from Ford Motor Company. It was a hybrid of two small-block Ford V8s - It used the block of the small Ford Windsor engine and the heads of the larger Ford Cleveland engine. It was created for the SCCA's Trans-Am road racing series, and was fitted to the Boss 302 Mustang.
The high nickel content block has a thicker deck, cylinder walls and beefy 4-bolt main caps. It is easily identified by screw in freeze plugs on the side of the block, pent roof valve covers, very wide heads and a very wide intake manifold. The connecting rods are heavy, high strength steel forgings made for high rpm use. The crankshaft is a cross drilled high strength steel forging. The cam and lifters are high lift solid mechanical units.
The unique, wide, large port Cleveland style 4V heads with poly angle, semi-hemi style valve placement are what give the Boss 302 its unique high power capabilities. Early units were typically characterized by very large intake and exhaust valves sitting in a small quench style combustion chamber. Huge intake ports made certain that the engine only "woke up" above 4000 rpm, while at low RPM the Boss 302 motor ran very sluggishly. At racing speed the engine's performance was quite remarkable.
