Re: [AMC-list] Fw: rambler problems

I believe all the older BW auto trannys used a torque converter with the starter ring gear made onto it. The front pump is identical in construction and design to the later models though. You should be able to use a 290 flexplate and torque converter with the M-8, but I don't know anyone who has done it.

Check the depth of the bell housings first. If they are close to the same (within 1/4") you should be okay. The torque converter must go into the trans far enough, but not put pressure against it. There is usually a 1/16-1/8" gap between the converter and flexplate with the converter shoved back as far into the trans as it will go. Should be no more than 1/8", and converter should turn without binding against the flexplate. If there is more than a 1/8" gap washers can be used to push the converter back, but you MUST make sure the bolts are long enough. I'd use lock-tight on them too. The converter centers on the crank with a "nose" on the converter that goes into a pilot bushing. There is no stress on the nose, it's just for centering. It needs to go at least 1/8" into the bushing. If washers are used an extended pilot bushing may be necessary.

You will have to use a 290 flexplate, or have a flexplate match balanced to an original 290 flexplate. The only way around that is to have the 290 internally balanced and use a neutral flexplate (late AMC six flexplate). That requires engine tear-down for balancing and may be costly though.

Some things you have to figure out for yourself. Someone on the list can measure the bells for you, but you'll have to get a 67-71 AMC M-11/12 torque converter (or an M-4x converter) and check it for fit in the M-8 pump. I think it will work, but that's all I can say.

hi eddie

i spoke with you  on monday regarding my  63 rambler wagon.  what i am trying to do is put a 68 290 out of my rebel into my 63 cross country wagon  that was originally equipt with a 287.  i have managed to get all the right component  except i need a tourque converter for my  borge warner m8 transmission.  i have a one peice converter and flexplate but it is a 176 tooth  andi need it to be a 164 to work with my 290. i have a flex plate i just need a m-8 converter that i can bolt to my flexplate. so my question in do the make converter that are not welded to the flexplate for the m-8 transmission and where can i get one.
