EDIT: what is a 4.10 ratio best used for i guess is my question ,, i seem to remember a fleeting moment of my adolesence wishing i had 4.10's for my street rod. and 4.63's were what i had in my prostock dirt car.. help ,, help me please
Joshua

Most owners would kill for 4.10's. That is an OEM gear set. 3.42 are standard and 3.73's or 4.10's optional. 4.10 is the perfect range for the 4.2L IMO. Fit the largest diameter tire you can to keep the RPM's down if you wish.

thank you sir.
