====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.
