    Fan shroud

    Hi all. A long shot I'm sure but if I don't ask! I'm after a fan shroud for my 1971 mustang 429 CJ. Its the same as the Torino 429 CJ. Ford part # DOOZ 8146D. A repro is fine and doesn't have to be new at that, so long as the condition is ok. The other thing is that I live in central France...

    Auto transmission stuck

    Help guys!  My 71 mustang has a C6 auto transmission. Nine months ago I ramped her to do some maintenance work. I did a transmission flush (7L of ford ATF) and changed the filter. I put in a Transgo 67 1-2 shifter kit too, a new vacuum modulator, a shorter pin and turned the adjustment screw a...

    What might have been done to my engine in the past?

    Hi All, Been a while and still working my way through a comprehensive servicing of my 429 CJ RA C6 Mach 1. Life gets in the way, as it does, and it's only recently that I've got a set of lifts to give me semi decent working room under the car. I just cleared some oil and crud from the engine...

    Rear diff oil change

    As slowly going through the car I thought it best to replace the rear diff oil. It's a 9" axle, so no drain plug - was it supposed to be sealed for life? Anyway fill plug out and then had to vacuum suck out the old oil using a brake bleed kit. Messy and slow and not helped as the oil was very...

    429 SCJ for sale in Europe

    Came across this today. £70k or about $87,500. No idea if it might be worth the asking price (and couldn't afford it anyway) but as so few are available across the pond? I also think they're being a bit optimistic with it's comparison and prices with Boss 429! 1971 71 Mustang mach 1 429 SCJ...

    Engine running lean

    I'm slowly working my way through my 429 cobra jet (had about 6 months). Noticed from the previous MOT (from UK though not needed it seemed prudent when buying the car) that there is a note saying that the car should be running richer than it is. Haven't pulled a plug yet to see but wondered...

    C6 vacuum modulator question

    I'm installing a Transgo 67 -1&2 shift kit into the C6 of my 429CJ. Thought I might as well replace the vac modulator too as no idea how long its been on the car. I got the scott drake c4az-7a377b one which has a white stripe. The old one has a white stripe too but strangely no little...

    Electric mustang from UK?

    From the car mag Autocar.  Why not I guess and if you have £300,000 you don't need..... Hopefully they won't refer to it as a 'muscle car' cos it certainly won't qualify for that status! London-based Charge Automotive has confirmed that its electric Ford Mustang will make its debut at next...

    Engine capacity conundrum

    I've gotten around to registering my 429 CJ in my name and on checking the registration document find the engine size is listed at 7850cc (rather than 7000cc). On looking back over old paperwork the earliest reference I have is from the 1988 registration papers with this capacity. OK this could...

    2 chamber muffler choices

    I'd like to change the old exhaust system on my 1971 big block 429 CJ. I'm keeping the iron headers (for ground clearance) and prefer the 'dugga dugga' sound of 2 chamber type mufflers rather than turbo's. Guess that means something like flow masters (40 series, super 44, super 40 or delta 40's)...

    electrical connectors on collant hose?

    I've started to go though my 1971 429 cobra jet and haven't been able to confirm what exactly is missing from these two spade connectors. Can anyone shed some light please? Thanks.

    Towing

    There's a classic car club locally that I hope to join soon. Should be great for drive out's from the spring onwards. Just one thing that concerns me a little though. Some of the drives are to Chateau's and country houses and parking is likely to be on grass. My car is a 1971 CJ 429 with C6 auto...

    Quickjack car lift - opinions?

    Hi All Has anyone got or used one of these car lifts by Quickjack? If so what do you reckon? What size is the correct one for our cars - the 70" or 75" frame length? (5000lb weight would be fine I'm sure).  Seems to be quite a good system from the reviews I've read in general and from you tube...

    Rebuilding rochester quadrajet

    My 429 CJ (ram air, auto, non AC) has a holley in place of the rochester as the PO couldn't get it to run properly. I've now, thankfully, received the original carb. It's been boxed up for the last 3 years, stored dry, though there seems to be a fair bit of rust and gunk on it. If it was...

    Steering wheel change

    I have the original, now non functioning, 3 spoke rim blow steering wheel. Although authentic it's such a thin rim and is quite large so I was thinking of changing it for a grant classic nostalgia wood one. Seems it comes as either a 15 inch or 13.5 inch with a near 4 inch dish. As I have power...

    429 fan shroud replacement

    Hi All. My 1971 429 CJ is missing its fan shroud. It's a non A/C car. I've looked on line and there seems to be two versions that get mentioned:- D0OE-8146-D and D0OZ-8146-D. I've not been able to find out what differences, if any, there are between these two. Would anyone know if either will...

    Rochester vs Holley

    My 1971 mustang 429 CJ has a holley 3310-12 carb fitted instead of the original Rochester. I presume its a 750cfm? It's on the original spreadbore iron intake with the appropriate conversion plate/spacer. It was fitted as the PO couldn't get the Rochester to idle at all. I gather the rochester...

    Under hood and gauge readings

    Hi All, Just getting to grips with my 1971 429 Cobra Jet Ram Air automatic mustang. Original condition with 52,000 miles. Has only covered 500 miles in the last 15 years as was part of a car collection. Full service, repaint and slight restoration 3 years ago. Trying to figure out, and hoping...

    New Owner

    Hi All. I've joined the fold! Just had delivery of a 1971 Mach 1 429 Cobra Jet Ram Air in bright red. Originally built for export to the UK where she spent all her life - until yesterday. Now she is in central France with me and my 2 dogs :) She is in original condition and has only 52,000...

    429 valves and petrol grade

    Hi All. I've been checking on this forum (and others) to see what opinions are as to the valve life of a 1971 cobra jet ram air 429 seeing as the original premium gas long since went out of production. The engine is original with 52,000 miles on it, runs sweet. I put 98 Octane in her (European...
