Isn't that just a long tail shaft turbo 350 with BOP (buick olds pontiac) bellhousing ? Turbo 400 size rear yoke ?

I don't know, I was reading one of my car books from are years and under the section which tells you if the car can be started by pushing there was a listing of and the TH's and it clearly said TH-375.....

375's got the internals of a TH400 (mostly) but the output shaft of a TH350. I think they came in vans and taxis, maybe a few buses too. good stout tranny's.

I've heard of it,I understood it to be a longshaft 350 also.

I found this,intresting reading

Quote:

THM375B - This trans is identical to the THM350, but is considered a heavier duty transmission.

THM375 - This transmission is a derivative of the THM400 sharing the external appearance of the 400. It'll be marked 375-THM on the bottom of the tailshaft housing. It's a light duty version of the THM400, has ABSOLUTELY NO RELATION to the THM375B, and was found in 1972 to 1976 full-size cars. The Turbo 375 was modified to accept the Turbo 350 driveshaft yoke.
