All speedos were set for 1000 rev. per mile. The gearing is adjusted to allow for gear ratio & tire size by the gears in the transmission. If the odometer is correct the speedo should be also. If not the needle is not set or adjusted right. Let us know how your adjustment goes. I use the mile markers on the freeway to check the odometer accuracy.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
