Now, if you have any idea of how we can talk this bloke into swaping me the 3.31:1 from his 84 into my auto 94 with 2.59:1, please pass on your thoughts!!
Ply him with alcohol and women.
Oh, and CFI-EFI, I was trying to be funny with my WC Fields quote. In hope you took it that way. No offense intended.

Checked out my RPM at cruize on the way home from work tonight, a shade under 1,500rpm for about 90kph, 94-96 kph is right on 1,500rpm, and 100kph (about 63mph) was around 1,550-1,600rpm. My 94 has a 2.59:1 rear.

When I got my build sheet for my 87 vert automatic, I was suprised to see that it came with a 2.73 gear.
It has just about every other performance option though.
Was this a common ratio for these cars?

But it is. With the 3.06 1st gear ratio of the auto trans, it resembles an old turbo 350 trans with 4:11's. Lately, I have been running the 3:33's. They came in my dana 44. For an all around gear(with my combo) they seem pretty nice.

Is that possible? What does this mean?

My comment of the "G92" (3.31 :1 gears) first requiring the Z51 option was only intended to address 1984, and apparently THAT is wrong.
