I ran P/G splined inputs for years and never broke one. In S/G type doorcars and in a dragster that ran in the high 7's.

I put another dragster together a few years ago and used a P/G splined input.....and it's a long story why I did that so I'll skip that....

I bought a good trans from a well known builder. He said I should be fine as I already had a P/G spline converter....I felt it always worked in the past so why not use it....

20-25 runs and I broke an input for the first time ever.....broke the splines right at the converter end on the starting line. I received a free replacement and it was definately a better input than the first one. Ran it with no issues after that. That was probably a Vasco Input.

I had my stuff upgraded since that event....had the converter redone and went to the turbo shaft and sold the p/g splined inputs I still had...

Converter was converted to spragless at the same time it was swapped to accept the Turbo input......If you were to just do the converter swap from PG to Turbo you'd spend probably $ 300 and have to buy an input for another $100+

Maybe the old inputs we had were better than the stuff out there today and everyone knows there is a lot of offshore steel being used in everything.......The input I broke did not appear to be very good material....
