I think the GP trim generally got something like the 2,87 as standard. Catalina usually had more like a 2.69 but the factory in 61 (like for GP later) thought that was a buyer that wanted a little more first gear go. Then there was the economy buyer who got like a 2.56.

There are a lot of rebuild upgrade levels that can be had for a TH350. And in general a TH350 can handle the Pontiac torque unless you have a fully built engine. When the TH400 came out it became standard for the B body Pontiac. After the 350 was introduced it was standard behind a lot of Pontiac engines in various body styles. . I told them to give me maybe one step better than a conventional stock rebuild.. I haven't beat hard on in yet and maybe never will but so far I'm good.
