Dually guys- When did 454's get TBI? preferred year?

I am again searching for a crew cab dually...and I was trying to figure out what year TBI started.

I was also wondering if there was a preferred year? and- What was the standard gear ratio?

I would imagine the newer the better....I am thinking that maybe the 91's had OD, but they are HARD to find. I plan to pull my car to/from the track and car shows. (~6000#) I would love a GV over/under, but I think I'll more likely change the gears to a hwy friendly selection.
