Gear Ratio Question

[bigjake34452]

i was just wondering what you guys think would "most likely" be the gear ratio for my truck. its a 69 F-100, 300, 4spd. 2wd. i went to look and the metal tag is gone, just thought i'd ask, thanks.

Best guess: 3.70, being a 300L6 I would think a customer would have likely ordered that gear.

What does the door tag say, last 2 digits on the second line.
09 would be 3.70.
08=3.50

doors says 08, thanks for the info!

Cool, you should be able to get that 300-6 driving nicely. And your mileage shouldnt kill you if its tuned up and is a decent engine.
(Think 15 mpg).
