Can someone decode this for me? Need a 727 for my ‘78 440. Thanks!
400 engine, standard perf, non lockup trans. Should be the same as what you would use with a 440, if non lockup is your goal. HTH, Lefty71
Does it provide the year?
1978, so it sounds like a really good match IMO. Don't know the accuracy, but looks reasonable; http://board.moparts.org/ubbthreads...rans-part-numbers-1969-79-plus-amc-72-79.html
You may want to check this too, for clarity on both units; HTH, Lefty71 https://moparforums.com/forums/f82/727-lock-up-converter-14856/
I've seen destroyed trans before - but''' Try and find a HP trans or pickup if you are going to rebuild else grab one from a C body or imperial- usually not hot rodded year makes little difference if you find a lock up all the better
Looks like it’s a non lockup. I can get it for $200. No TC. I’m building a stockish 440 for shows and power tour. No racing. For my application, does it matter if it’s lock up or not?
That number lists as from a '78 station wagon, 400 cid with a 4bbl carb. For $200 I'd get it! (If it's not bleeding parts out of the case lol)

for your application not really lockup has a little better gas mileage, several hundred less rpm at cruze and runs cooler, you can also run a looser converter and still have it lock up- the factory lock up converters were looser to give more torque multiplication for the absolutely no bottom end of the late smog 400s and 440s- without the lock up the factory would have had to lower the gear ratio- and then they had to do that too!
Thanks guys. Got it for $200. Hope it’s good! Fluid is red, shifts thru the gears, and tail piece rubber boot is still rubbery
