thm 250 has oval holes in bellhousing
-----
the 350 has a square pan with one corner flattened
and it has 13 bolts the the pan.
The speed governor in a thm350 is a centrifugal device with weights and springs altering this device is tricky .Try the after market.
out of the two, you'll find that the thm400 is a better transmission all around. it was a more heavy duty built transmission than the thm350, and it does last a lot longer. we had built up a 77 gmc sierra classic with a 350 4 bolt, and it was pushing near 500 hp. tore apart 3 thm350's before going that little bit bigger, never had a problem with the used 400 we bought. just from my experience, the 400 is a better transmission, a little harder to come by, but much worth looking
I believe its 300hp with 380fpt. Just like a 67 camaro running a 350 SBC and thm350 transmission
No you cannot tell the difference between two. It is similar that is there is no difference in mails. No such difference is written.
Telling the DifferenceYou can tell the difference by the area of the body that is affected.
how can you tell the difference between a tortoise and a turtle by shell in picture
Can you tell the difference between Vyvanse and Concerta in a drug test

No difference
You have your doctor tell you what you have.
