swap 400m to 429 problems

alright. i have almost everything...got the motor in and got all the stuff ready to roll to put the c6 tranny up on the 1970 429 motor....the transmission wouldn't draw up. after a while we realized the snout for the torque converter was wasn't going into the end of the crank...so in this matter i really need a straightforward answer.

can i put a car torque converter in the c6 even if its 4x4? not really sure if it would matter or not but just making sure so i don't spend more money than i have to...

or
is there an alternative. and i know its not a pilot bearing since its not copper

Pilot bearing only used with M/T and they're not always made of bronze (copper too soft, wouldn't last a day). Some are sealed bearings that internally, have a dozen or so needle bearings.

Uh huh, take a look-see at A (Galaxie/LTD) 429 M/T application.

F/4/S = Ford 4 Speed, same trans installed in V8 Mustang/Cougar/Fairlane/Torino/Comet/Montego and etc.

Um sure it does. Like he stated a pilot bushing or bearing was only used with a stick so it isn't even relative to your situation.

As far as a 429 is concerned there were 3 different hub pilot dimensions for the end of the crank. I have no idea if there is a difference between a car/truck converter but if it were me I would order a new converter to eliminate the possibility of having to tear it apart again to replace.

No truck converter, cuz 429's were only installed in misc 1968/73 Ford/Merc passenger cars, 1968/71 Thunderchickens.

Correct, completely spaced that part.

So to answer the OP's question he must go with a car converter. When I did my swap I ordered a new TCI converter, I think it was right around 150. Mot worth using an old converter. Just check the pilot hub dimension.

Awe man... I wish I realized this sooner. 😂 Just spent most of the day trying to figure out why my new 429 wouldn't snug up to the c6 in the camper special. Guess I'll be out looking for a new converter

Gator McClusky drove a 429 4speed LTD.

Glad you found your answer though, car converter will do fine ... just "had to".
