" Now Andrew, that's a big slip for you!! Yes on the manual OD trannys

i -thought- that was the case...

btw the last warner o/d i know of was also on a t89, behind a 390 in
the '71 ford pickup.

" but ROCHESTER injection? The 57

oops.  i should've known...  it was a late-'50s poncho that got the
rochester - if i'm not wrong there too...

at least i remembered they had injection!

it's rather ironic that they didn't stick with it, because that system
did indirectly kick off the modern age of efi - when bosch bought the
patents from bendix and developed a successful version, introduced on
the '66 vw squareback 1600.  my aunt had one, for about ten years
iirc.  one of the last saabs my parents bought, a '71 99, had it too;
the other, a virtual twin but with carbs graphically illustrated the
difference.  the injected car ran better, was more responsive, had
more power, got better mileage, and took cheaper gas without pinging.

it was a critical period in transistor development though, and bosch
undoubtedly benefited from that.
