Good rear gear ratios. (By vehicle weight)?
So I recently started a project.
I'm dropping a 12a into a 78' Datsun 510 wagon.
When it's all said and done, the total weight should be around 2300lbs.
The Datsun rearend has a 3.30 gear in it. Thats a bit steep for a 12a street port IMO.
I know the factory gear ratio of an FB is 3.90. But with the added weight I would have to think that a lower ratio would be better?
I'm going to run 165/50r15 tires.
Does anyone have any feedback with experience on this?
The lowest gear I could get for the Datsun would be a 4.10. But I have to wonder what it's street manners would be like with that low of a gear??

The 3.30 gears are way to steep for a car that size with a 12a, I know that much.
If anything I'm going to drop to a 3.90 gear. I was more curious about the street manners of a 4.10 gear behind a 12a??
cause I can run that gear. But if that's to low, I don't want to waste my time on it.
