What servo does my C-4 have?
 

Which servo came factory on the C-4 trannys? I have a '78 C-4(case fill) and I want to do add a manual valve body and upgrade to either an "H" or "R" servo. I was wondering which one it has already.
Also, where is a good place to buy an upgrade servo?
Which one would be better...the H or the R servo?

Does anyone know the answer?

I think what we don't know is the difference in "H" and "R" servos. I do believe that there are two different servos, some being race oriented. My bet is that there is an '"R" for race servo of some larger diameter that delivers stronger shifts. I think these are available from the after-market. My belief is that these would be the "R" servos and that the "H'" servos would be the stock ones. This is all complete conjecture.
