TH 350 transmission...

Help Support Ruger Forum:

It will fit the straight sixes, the 4.3 V6, V8 small blocks, as well as the " Iron Duke" four.
Just be aware there are two tail shaft lengths.
 
Like Markallen said check the length of the tailshaft(extension housing). IIRC there's 2 different lengths About 4-5 inches different.
Swapped tranny's in my 74 C10. All went well until I went to plug the driveshaft into the extension housing.
 
I think Chevy went to the same bellhousing pattern for the 6 and 8 in the early 60s. Pontiac/Buick can be bolted up with an adapter or by cutting part of the bellhousing off the trans
