Ford Mustang Boss 429

The **Boss 429** is a hie performance Ford Mustang variant affered in 1969 an 1970.

## Overview

The Boss 429 is arguably ane o the rarest an maist valued muscle caurs tae date. In tot thare wur 858 oreeginal Boss 429s made.  The oreegin o the Boss 429 comes aboot as a result o NASCAR.  Ford wis seekin tae develop a Hemi ingine that coud compete wi the famed 426 Hemi frae Chrysler in NASCAR's Sprint Cup Series (then kent as "Grand National Division").  NASCAR's homologation rules required that at least 500 caurs be fittit wit this motor an sold tae the general public. Efter much consideration, it wis decidit bi Ford that the Mustang wad be the caur that wad hoose this new ingine.

The Boss 429 ingine wis derived frae the Ford 385 ingine.  The Mustang's body houiver wis no wide enough tae encompass the massive Boss 429 ingine an as a result, Ford hired Kar Kraft oot o Dearborn, Michigan tae modify existin 428 Cobra Jet Mach 1 Mustangs tae properly fit the new Boss 429 ingine.  Kar Kraft wis contracted bi Ford tae creaut the Boss 429, acause Ford wis stretchin itself thin across a nummer o projects. Kar Kraft at the time wis in the process o creatin the Trans-Am Boss 302. Production on the Boss 429 began in 1968 in Brighton, Michigan at Kar-Kraft's factory; the caurs wur transportit tae this plant directly frae the auto maker's plant an the work began. Kar Kraft made extensive modifications tae the Mustang, includin widenin the shock touers an extendit oot the inner fenders tae allou this massive ingine tae fit. The mounts for the front suspension wur chopped an displaced tae creaut room for the block an exhaust manifolds. Next the battery wis repositioned tae the trunk an a stiff sway bar wis addit tae rear end. In addition, a hole wis cut in the huid an a manual controlled huid scoop wis addit tae thir caurs.  Thir caurs wur ratit conservatively at 375&nbsp;hp an 450&nbsp;lb ft o torque. Actual ootput wis well ower 500&nbsp;hp. The manufacturers an dealers anerlie listed 375&nbsp;hp acause o legal issues an risin insurance costs.

Baith model years featurt a toned doun exterior, as compared tae ither Mustangs o the era (*see* Boss 351, Boss 302, Mach 1), in that the anerlie external identification o the caur wur the Boss 429 decals on the front fenders, aft o the front tires.  The rest o the caur featurt a very clean leuk that wis atypical o maist Mustangs that Ford haed produced.

Tae shaw juist how special thir caurs wur, thay wur gien special NASCAR identification that wis placed on the driver's side door.  Each caur wis gien a "KK" nummer which stood for Kar Kraft.  KK #1201 wis the first Boss 429 an KK #2558 wis the last Boss 429 made.

Unfortunately sales startit tae drop off for the 1970 Boss 429 Mustangs an wi hichter production costs, gas costs, an ither internal Ford problems, it wis decidit that 1970 woul be the last year o the Boss 429.

In present day, thir caurs ar hichtlie sought efter.  As o 2008, auctions on eBay an at Barrett-Jackson hae brocht bids o ower $350,000.
