Location: Woolwich Twp, NJ (South Jersey) | Need some help here to see if I was a little hasty purchasing a bellhousing and adapter plate on E-Bay. When I purchased my car the engine was torn down including the bellhousing. The bell was not cared for during storage and the bottom alignment hole ear was broken off. The bell is from a 354 hemi with a Powerflite trans. I am preparing to convert my trans to a Torqueflite. I purchased a bellhousing and adapter plate assembly for a Torqueflite on Ebay without checking the casting numbers. I think I may have purchased in haste. Please help..
Powerflite:
Adapter Plate casting number: 1612344 (Mohawk)
Bellhousing casting number: 1559417 (CB 824613)
Torqueflite:
Adapter Plate casting number: 1736183 (Centr-O-Cast)
Bellhousing casting number: 1630793 (CB 25585 D6)
Regards,
Mike |

Both the adaptor plate and the bellhousing numbers for the Torqueflite are for a 1957-58 Chrysler with Torquflite transmission....... |

Location: Woolwich Twp, NJ (South Jersey) | Hank - Thanks for the help. The one item I forgot to ask is; will this T/F setup fit on to my 354? When comparing the bell and plate the bolt holes do not line up.

The plate and bellhousing have different bolt patterns, or the bell to the transmission has different pattern?
Be real specific by part number to part number as to what doesn't match up, as otherwise, you will need to send me pictures...... |

When I place the T/F plate on the P/F bell, the T/F plate is shorter in length and the starter centers are off. I used the upper bolt holes in both the bells and plates to verify bolt hole locations. The bolt holes of the upper 180 of the bells and plates match including the oil galley access openings in the plates. The starter centers are different and top to bottom length of the P/F setup is greater. I have attached pictures to help clarify. Sorry for the confusion. Will this T/F setup work on my 354? And will the difference in the starter center be an issue. My motor is still in the machine shop so I cannot check the fitment.
Regards, Mike

I think I see what you are trying to do.
You want to use the 354 adaptor plate with the Tflite bellhousing?
If so, then that may not work.
My setup on my car is to use the Torqueflite with the Powerflite bellhousing and adaptor plate.
This was done in my case on my DeSoto due to the starter change from 1956 to 1957.
So I needed to keep my 146 tooth starter. The Torque converter got its ring gear swapped over to a 146 tooth one, and I now have a loose 172 tooth ring gear as a result.
I know that in any case I was going to have to modify the driveshaft, but the thin adaptor plate and the Pflite housing (water cooled version) should at least make the rear trans mount sit somewhere near where the Powerflite's location was.
As you are going to have to do similar, you might just use the 392 adaptor and housing, as it allows you to use the later starter for the 172 tooth TC that I expect you have.
Or, as I did, go to the Pflite bell and adaptor. You in this case also need to make a new retention bracket for the trans oil fill/check tube.

I agree that I will need to use the 392 T/F setup since the P/F bell has a broken ear at the lower dowel pin location. You brought up a good point with the tooth count. The T/C that I have is a 146 count and the original starter from the 354 P/F setup. The T/C and transmission is from a 57 Imperial. With the starter centers being different between the P/F and T/F will that be an issue with the count?
The other item I still need to resolve is the driveshaft issue. I need to find a slip yoke setup or a B&T for this 57 trans. The B&T from the P/F will not work with the drum on the T/F. The bolt centers and splines are different. I believe I need to cut the shaft approx 4" due to the P/F and T/F lenght difference.
Regards,
Mike |

As I was able to put a Powerflite 146 tooth ring gear onto the Torqueflite converter (simple swap, both are same diameter for that dimension), I think that the Torqueflite bellhousing and adaptor plate would HAVE to end up locating the starter from in the same radial offset position for the tooth engagement. The absolute polar dimensional position WRT the crankshaft C/L might be a little different (trying for some clearance, so swing the starter up?), but it should work....... |
