I have a 1955 f-100 and a 351 windsor with an fmx. i already have the fmx up and operating. i was wondering how much trouble it would be to swap it over to aod. as far as driveline and bellhousing. then the shift linkage and passing gear and all of that stuff. i have very little knowledge and would appreciate all the help i could get. thanks
FMX and AOD control throttle pressure by different methods.
FMX uses engine vacuum and AOD uses linkage only.
The kd for the FMX can not be adapted to the AOD to control it.
There are several different lengths of FMX so without knowing what you have it is impossible to say if you will need a different length drive shaft.
As for the yokes they use different ujoints so yours will have to be cut to accept the alteration or get a different shaft.
well i got an edelbrock carb so could i get a linkage from lokar that would work?? as far as bell housing bolts they r the same right?? and the fmx is out of a 79 thunderbird. so that might tell u what size case it is.
so if i had the yoke out of the aod i could use my shaft if i had the same joint to combine it with the driveshaft?? how hard is it to adjust the linkage to get it to work properly?? is the aod a lot fatter than the fmx?? my pipes run down beside of the fmx now. it shouldnt be much wider than the trans now. how much difference is there in the yoke of the aod and the yoke of the fmx?? does the aod have a bigger u joint or what??how is it set up??
so as far as cutting the shaft i wouldnt have to just have to change end to fit the smaller u joint. i found some measurements on the fmx and aod and was curious i they were accurate. aod overall 3 3/4" and fmx overall 30 1/4"
The Length & width are close. The yoke is different. I bought A U-Joint from Advance. Looked threw there book & compared the sizes. Found One that worked.
There is Width & Cap size. You must know where the shaft & yoke came from.
You will not find a Carbed Car with an AOD. The 85 had the VV induction.
Similar to a carb. But didn't use a cable system. It used a Kick-down rod.
I run a 351W & the AOD in my 1990 Thunderbird Factory Stock Oval track car.
I am still trying to get the linkage right. Tried the kick-down rod but the 351w
is too wide for the rod. I went to the cable style but couldn't find a carb end linkage bracket. Made my own, still not right. I manual shift + I run in second gear. The only reason I took the FMX out was that I broke it.
I T-boned another car that spun out in front of me. Broke both Engine Mounts & the trany mount. the shifter cable & gas pedal cable held it back. Bent both brackets. The carb went to WOT & the trany hit R.
so paul will the lokar cable work?? or do you know have u tried it?? thanks for the information. so it is possible to get a u joint that will match my shaft i have now and the joint for the aod yoke?? did u have to move ur mounts or anything??
