th 350 question
 

why do some race TH350 trans use a PG input shaft? tks.

Re: th 350 question
 

In my case, I switched from a Powerglide to a TH350. All my converters are glide input. Didn't want to buy all new converters.

Re: th 350 question
 

Same here, wanted to use all of our conv from the glide.

That was my first thought too, Jeff.

It's actually much easier to put a hardened 30 spline input shaft into a PG, and use a T350 converter. Those shafts have been around for a long time.
I guess there are a lot of PG converters out there still.

Re: th 350 question
 

I had PG input shafts for years in various cars with zero problems. Put a car together and bought a trans and used the PG input to fit converters I had. Less than 20 runs, broke an input. It was a 300M input supposedly. I went to a much better input and it never broke. Changed all my stuff to Turbo inputs some time later and sold everything that was PG splined.
