Rearend Gearing

Does anyboby know the gear ratio on a 68 F100? It has a 240 with a C4 and the rearend is a 9 inch. I'm thinking it is either high 3's or low 4's. Thanks

Probably 4.10. My '70 F-100 came with a 240, C4, and 4.10. Now has a 300 I6

Thanks, mine now has a 302 and it lights up the back tires like a roman candle. Instead of changing the gears I think I'll just put some fat tires on it.

Look at your drivers door. There should be a tag on the door as soon as you open it you should see it.
There will be approx. 3 rows of numbers.
Let us know what's on them.
