The Ford big-block engines of the late 1960s became the epitomes of unbridled, raw racing power, and even today, enthusiasts refurbish these awesome pieces of automotive technology. Of the 427, 428, and 429, the Ford 429 engine is one of the most technologically robust big-block units Ford has ever made. The Ford 429 engine features a thin wall casting, huge bearings, canted-valve cylinder heads, and much longer bore centers than the other FE block engines. It is a unique motor, capable of achieving optimized performance – where the valves being angled in the head allow much larger ports and valves than on other engines, facilitating better mixture of gasoline and air in the chamber. Boss 429 engines are in 1969 and 1970 Mustangs, being rare, regarded derivatives of the powerful 385 engines. Within such a vast inventory on eBay, you can track down many of these engine types and variants, including the 429 Cobra Jet engine, which features steel rocker arms, a compression ratio of 11.3:1, a cast-iron intake manifold, and bigger heads and larger ports and valves than earlier designs, achieving a staggering 370 horsepower rating. The Super Cobra Jet upgrade has other markedly improved features, such as forged aluminum pistons, external oil cooler, and a cast-iron crankshaft with a much higher nodularity than the standard 429. While the 429 engines ceased production in 1973, they are frequently used in car builds today.Shop the large inventory of motors, parts, accessories, and complete Ford car and truck engines!
