What trans came stock with a 1977 Formula 400?

It would likely depend on the engine/trans package spec'd,but could have been TH350,BW ST-10 or possibly Saginaw?

Does it have a clutch pedal? W72 option?

Stock automatic was a TH350 in that year. On a manual it would be the BW ST-10 as I am not sure the Saginaw was used behind the 400, but it very well could have been (not really sure there).

If it is an automatic, it supposedly can only be a th350, has to do w/ the cat. converter.
Hot Rod magazine had an article w/ a prototype 1977 T/A, it had a TH 400, but none came in production models......if my memory is correct... I still have that magazine somewhere...

I remember a yellow 77 Formula used back then but it was 4 speed non air car.They also pulled the belts and drop the exhaust at the convertor and it ran 14:20's.

I have a magazine with that roadtest, I swear it was an automatic TA 6.6 Formula with 3.23's... 14.2 @98 with open exhaust and air cleaner removed..
