3 speed conversion?
I was wondering if anyone might have info or links about converting a 3 speed column shift into an automatic style steering column?I found a bunch of info on converting the 3 speed to a floor shift,but nothing on converting to an automatic.I know it can be done.An old timer who was helping me out with my engine build said there easy to convert and That was a popular conversion back in his day.But he recently died.Thanks,pat

Re: 3 speed conversion?
Depends which auto tranny you want and what motor you have. But here's some info I put togethor that will help you.
Any other questions to clarify it all just ask. http://67-72chevytrucks.com/vboard/s...d.php?t=631139 |

Re: 3 speed conversion?
You can likely find a flexplate or a new starter drive to make the connection.
You'll need a tv cable set up on whatever carb you use. Check here for that info. http://www.bowtieoverdrives.com/index.shtml If you don't use a different steering column for an auto tranny then Lokar among others make some nice floor shifters. |

Re: 3 speed conversion?
454's are externally balanced and need a weighted flex plate. They are rather inexpensive new.The 400 small block is the same flex plate.

Re: 3 speed conversion?
No a 400 small block and a 454 big block are both externally balanced. However the flexplates are not interchangeable they are balanced differently.
