what ratio works best with 350tpi 1988 year ,auto,also looking for gears for 9bolt have 2.77s now, hate them! call608-606-4760

 

I would say a 3.08-3.42 would be the best, depending on the mods you plan on doing. But remember, these cars in stock form, don't breathe past 4500rpm, too much gear can hurt more than help. If you plan on staying stock I'd say 3.08's.
