Editing Ford 385 engine (section)

===429===
Introduced in 1968, the 429 was developed in conjunction with the 460 (also debuted in 1968) to replace the three largest FE-series V8s, the 390, 427, and 428. Both had wedge-shaped combustion chambers and shared a 4.36-inch bore, with the 429 destroked to 3.59-inches.

The 429 first appeared in the Ford Thunderbird, getting a one-year head start on other Ford and Mercury models, and saw use across both divisions' pony car, intermediate, and full-size product lines. It was also later available in high performance [[#Cobra Jet|Cobra Jet]] versions for street use and police interceptors.  A race-bred "[[hemispherical combustion chamber|semi-hemi]]" version for NASCAR competition was developed and installed for homologation purposes in the 1969 [[Boss 429 Mustang]].  

The 429 was replaced in 1974 by the 460 in Ford and Lincoln-Mercury cars, and only available in medium-duty Ford trucks after the 1973 model year.

The engine became marketed in metric in 1979, as the 7.0L V8.<ref name="OCB79"/> Initially replacing the 401 [[Ford Super Duty engine|Super Duty]] V8, the 7.0L replaced the 477 and 534 Super Duty engines for 1982. After 1991, the 429 became the sole gasoline engine offered in medium sized and larger Ford trucks; the 460/7.5L was only used in trucks under 1½-ton payload.

====Boss 429====

A race-bred "[[hemispherical combustion chamber|semi-hemi]]" version of the 429 was developed for NASCAR competition, and installed for homologation in the [[Boss 429 Mustang]].  This was a very different and much heavier duty engine than the standard 429, and distinct from the two high-performance wedge-head Cobra Jet versions.  Designed to compete with the reigning most powerful street V8, the [[Chrysler_Hemi_engine#Second_generation:_426_1964–1971|Chrysler 426 Hemi]],<ref>[https://www.hotcars.com/boss-429-and-426-hemi-compared/#:~:text=The%20Boss'%20Emergence,base%20model%20inline%2D6%20Mustang.

The Boss 429 Mustang and [[Mercury Cyclone Spoiler II]] were the engine's only street application, but it competed in NASCAR installed in various Ford and Mercury products, including the Cyclone Spoiler II and later builds of the [[Ford Torino Talladega|Torino Talladega]].  It took home 26 winner's trophies in 1969, before factory support was curtailed going forward.<ref>[https://www.hotcars.com/legendary-60s-muscle-cars-that-took-nascar-to-streets/ 10 Legendary '60s Muscle Cars That Took NASCAR To The Streets], hotcars.com</ref>

====Cobra Jet====
In addition to the NASCAR-bred "semi-hemi" used in the [[Boss 429 Mustang]], Ford developed two high-performance street versions of the wedge head 429 between 1969 and 1971, the Cobra Jet and Super Cobra Jet.<ref>[https://www.slashgear.com/1665519/boss-429-super-cobra-jet-engine-difference/ Ford Boss 429 vs 429 Super Cobra Jet Engines: What's the Difference?], slashgear.com</ref>

The Cobra Jet (429CJ) was fitted with a [[Rochester Products Division|Rochester]] [[Quadrajet]] {{cvt|715|cuft/min}} Spreadbore 4-bbl carburetor, a larger camshaft; a special set of cylinder heads (DOOE-R) 73.5 CC, combustion chamber and canted valve configuration, with pushrod guide plates (DIOE-6465-AA) Intakes valves were 2.24 and exhaust valves were 1.74, with non-adjustable hydraulic lifters. This allowed for an 11.3:1 compression ratio, increasing output to 370&nbsp;hp. The engine was fitted with or without a hood scoop, matched with a 3.25:1 rear-axle ratio. When fitted with a "shaker" hood scoop, a 429 CJ-Ram Air equipped vehicle received a 3.50:1 rear axle. In 1971, the CJ engine also used a four-bolt main block DOVE-A.
