Hi all! Well, after reading several posts on the matter, I have decided that I should change out my ratios before going with my 35s. I have a 350 and a 700R-4 (I think: there is an "automatic overdrive" sign over the indicator), my Jimmy is an '82. Which is best, 4.10, 4.56, or 4.88s? I know that in my Cruiser 4.10s were optimal with a V8 and 35s with an sm465, but now I am clueless. Also, is the r&p swap something that I can do myself, or should a shop do it? I have put in numerous lifts, put in a jillion stereos, changed out hubs, etc. I am not a novice mechanic, but I am no expert either.
