I've heard I need to reverse the lines on the transmission side when going to a TH350 from a TH200 metric, is this true?

Could they stay the same on the radiator end too, or do they have to be changed around as well?

For the radiator follow the in and out corresponding with the trans.

Out on trans to whichever is in on the radiator and out on rad to in on trans

For the cable I bought a universal one from amazon which is sold by most trans places. Factory ones are hard to find. This had good adjustability for length.

Will that work for a Th350 as well? I assume so since you linked it. Just want to be sure.

Do you, or anyone, know what length kickdown/detent cable I would need? TH350 into '85 Regal. Buick 350. Stock intake and Qjet off a '78 Buick 350.

Kickdown would be engine/trans combo defined.

Just buy one for the donor car (78 Buick xxxx with 350/TH350), it only runs from carb to trans and does not care what chassis it is in.
