Thanks RRR, I looked it up after you posted "FMX". Don't have no need for a FEORD transmission even if is only $25. But that 727 BB tranny could be resold for a $100 I imagine??
$100 is pushing it by the looks of it. I wouldn't pay more than $50 myself cause it just looks like a crusty parts trans. The only thing that might make it more valuable is if it was from a 440 six pack or hemi car. You'd have to look on the drivers side right above the pan rail and get the #'s off to verify what it's really out of.
Like RRR said the easiest way to identify a SB from a BB trans. is the big block trans. has four 1/4" bolts right at the bottom to hold the dust cover on and a SB only has two 1/4" bolts going through the dust cover. The dust cover on a BB also comes off without removing the starter. A SB requires removing the starter to get the dust cover off.
