Does that sound about right with 33's and a 4.0?

Auto combined with 4.10s isn't enough gear, you need 4.56s.Its a stock dana 28 from 89 so i guess it would be 410's. The transmission is auto and i'm driving it 55 miles exactly on the highway. I measured the distance using another car, my trip is still wrong cause of the 33's.
Like 14, but I do 70+ and I'm turning heavy and aggressive super swampers.What are you getting with the 4.56s highway?
I would like to point out that we don't KNOW that he has 4.10s. 3.45 was a much more common ratio that year.Auto combined with 4.10s isn't enough gear, you need 4.56s.
I agree, I was thinkin 3.73's. That's what my 90's have.I would like to point out that we don't KNOW that he has 4.10s. 3.45 was a much more common ratio that year.
Has nothing to do with year, if it was a factory auto, it should either be 3.73s or 4.10s, and it's a moot point, because it still needs 4.56s gears, which we know it doesn't have.I would like to point out that we don't KNOW that he has 4.10s. 3.45 was a much more common ratio that year.
