C4 Specs?

[richardsdd]

I have a C4 in my car right now, but I'm unsure what year it is. I just changed the filter and fluid for it and I know it isn't a 69-70 C4 because the filter design was wrong. We had the parts guy bring out a couple of filters to compare and the one that matched was a 74. Now I am sure that they used the same filter setup for multiple years, but can anyone tell me what the HP and torque ratings are for a 74 C4?

Thanks!

C4 was used behind everything from 2000cc to the 351W. Find the tag on the servo cover or get some engineering numbers off the converter or housings.
