Ok so im going to look at a new stang and the guy added 4:10's, but never corrected the speedo for it. so i was wondering how much faster a set of 4:10s add the miles on. Thanks for your help.

Common sense tells me if the speedo is off by let's say...15%..then the odometer should be off by 15% too.
So let's say he had the gears put in at 40k miles and the car now has 50k miles, then 15% of 10k should be "false mileage"
That's just what my gut tells me. I dunno though.
