Mach 1 1971 351c

[Ingo]

Lättast är ju att mäta,men visst var läppen ovanpå klumpen med genomslagsgummit ingjuten i 8" bakaxeln?.

På 9" är den ju skruvad..

Så jäkla länge sedan man pillrade med en 8" bakaxel...

[Nenne]

För min del tycker jag det här är det enklaste sättet att se vad det är för axel. Verktyget i bilden behövs egentligen inte men visar tydligare än 1000 ord vad som avses.

OK jag skall hålla ty-t, snart.

Vi talar om bakaxel som monteras på 71-73, den 8" ser

faktiskt ut som en 9" för den som har OVANT öga.

Jag skulle vilja att man tänker till lite innan man

skriver, givet går det inte i en 9"utväxling i en 8"

men det går i en 8" i en 9"bakaxel för ovanstående år.

Skulle vara mycket intressant och se en sådan axel med 8" kronhjul och pinion i ett 9" axel, är det någon som har mer info om det.Alltid kul att lära sej något nytt.

The Mach 1 for 1971 used a different grille/bumper combination than the regular base Mustang. The Mach 1 honeycomb grille housed two driving lamps while the front bumper was covered with urethane color-keyed to the Mustang's paint. Fender moldings were also color keyed. The non functional NASA hood was standard equipment. The hood along with the lower body were painted either black or argent, depending on body paint. Color keyed dual racing mirrors were standard and all Mach 1s came with front fender Mach 1 decals. There was also a small Mach 1 decal on the rear deck above the pop-open gas cap. Boss 351 type side stripes were optional.

In the interior, the Mach 1 came standard with the base Mustang interior. Optional was the Mach 1 Sports Interior, which was optional on other Mustang SportsRoof models as well. Besides the special seats, door panels, 2-spoke steering wheel and clock, the package included the instrumentation group which consisted of three additional gauges- oil pressure, alternator and water temperature, all housed in a panel above the radio.

Standard engine with the Mach 1 was the 302 V-8, and all other V-8 were optional, except the 330 hp 351 found on the Boss 351. Optional V-8s were the 240 hp 351 V-8, the 285 hp 351 V-8 and the 370/375 hp 429 V-8. All 351 V-8s were of the Cleveland engine family. In May 1971, a low compression 280hp 351 V-8, called the 351CJ, replaced the 285 hp 351 V-8 that was available at the beginning of the model year. Both of these 351s had the same engine code, M.

The 428CJ was replaced by the 429CJ as the top Mustang and Mach 1 engine. The 429 belonged to the Ford 385 Engine Series and as such, no parts were interchangeable with the older 428. Wider, larger, and heavier, the 429 would not readily fit into the 1970 Mustang engine compartment, which is one of the reasons why the 1971 Mustang got bigger. The cylinder block was a variation of the 429/460 block, of which the Boss 429 was also based on; the cylinder heads were similar to the 351 Cleveland in design. You could describe the 429 as a large Boss 302. As equipped in the Mustang, the 429CJ came with four-bolt mains, forged rods and pistons, 11.3:1 compression ratio, a hydraulic cam, (similar to the Boss 429's) very large ports and valves, and all 429CJs came with aluminum valve covers. The 429CJ came with a Rochester Quadrajet four-barrel carburetor, and some early units had adjustable valve trains.

The 429CJ became a 429SCJ if the Drag Pack option was ordered. It consisted of a 3.91 or 4.30 rear axle ratio with Traction Lock or a 4.11 ratio with a Detroit Locker rear. Both of these engines have the engine code C. Some Mustangs with the Drag Pack also included an external engine oil cooler, though of a different design than previously used. The SCJ engine came with a Holley 780 cfm carburetor rather than the Rochester Quadrajet, a mechanical lifter camshaft and adjustable rocker arms.

Although the 429s were available on any Mustang body style, the big engine was most often seen in the Mach 1, which was still the main Mustang performance model.

1,865 429CJ equipped Mustangs were built in 1971, most being Mach 1s.

Den ingjutna läppen som sitter på den högra bilden trodde jag inte fanns tillnågon 9" bakaxel?

men som sagt banjon kan ju se lite olika ut,och var pluggen sitter säger en hel del om årsmodellen.

När det gäller 429 så var det endast SCJ som hade smidda kolvar, dessutom en modifierad vev, svänghjul och svängningsdämpare. (finare balansering) 4-bultade överfall är också standard. Oljekylare ingick ej. Bakaxel 3:91 traction lock eller 4:11 detroit locker. Motor kod är C utan ram air och J med ram air.

både CJ och SCJ hade förstärka automatlådor med förstärkt planetväxel, extra lameller och R- servo samt gjutjärnsstrut.
