transmission swap
 

I have a friend that wants to convert his 1957 chevy FROM a powerglide TO a Th350, his 57 is a inline 6 cylinderwhere can he acquire an adaptor kit?

I think it'll bolt right up. May have to modify the crossmember a little...

I agree but don't think you will have to modify the cross member at all but let us know if or of not...Thanks

TH350
 

IF the TH350 has a Chevy bolt pattern and has the short tail shaft, then it is the same length as a powerglide and will bolt right up. But some TH350's do come with an intermediate tail shaft or a long tail shaft, not to mention having a Pontiac/Olds/Buick bolt pattern case.

Make sure that the flexplate has the extra bolt holes to match the lugs on the TH350 torque converter. Sometimes the flexplate has only the one set of holes and needs to have the other ones drilled to match the converter.

Back when I had my 63 Nova, I put a TH350 in it. Had to trim the front of the crossmember a little to clear the trans pan. Otherwise it bolted up fine...might not be an issue on other cars.
