3.73s or 4.10s work good with 35s.My 86 runs about 2500 at 100k (62mph) in direct.I'm not a fast driver & this truck spends 50% of the time on dirt/gravel roads so it works good.I ran 3.42s behind a 6.2 two years ago on 35s but that was almost too tall.My 82 with 6.2/3.73s & 35s works good too,if I get into mud or snow,just throw it into low range. The 80 K20 has a 454/465 with 4.10s on 33s,but 3.73s might work better for it.Pulls good though..
