What are the 3rd gear ratios for the C4/C5/C6 ?

85 F150 3sp. auto. orig. 3.08 rear, orig. 300/6 now 95 302HO.

I believe I have a C5. At about 70mph I'm turnin 3000+RPM. I going to a 3.55 rear (the 3.08 won't leave a stoplight) which would increase my revs at 70mph to who knows what. With a 3.55 rear I would need a AOD for the hiway. I was wondering "what if I used a C6 instead of an AOD, surely a C6 must have a higher 3rd gear and that would allow me to run the hiway now and then." C6's are plentiful w/out the expense of modding a AOD, right?

Thanks,
Meaux

I think they're all 1:1 or thereabouts. The first two might be different but the 3rd gear is probably the same on all three. This is just a wild ass guess though, somebody around here probably knows for sure. Good luck
