Lookin for input on if i should keep my 3.73s or switch to 4.10s with my set up.. Lookin for the fastest 1/4 can get.. I shouldnt lose to much up top should I..

 

What do you mean by "top end".

Top end as in highest mph possible

or

Top end as in 3rd gear charge at the end of the 1/4mile?

theres only 1 tooth different between the 3.73 and 4.10 GM gearing.
4.10=41-10
3.73=41-11

You might not even notice a SOTP difference. I went from 3.08's to 4.10's and it wasnt "nightand day crazy" like everyone said it would be. dropped 3-4 tenths in the 1/4 and lost 2 mph.

If your turbo'd and especially if your turbo'd with nitrous I'd go with 3.73s without a doubt... I ditched my 4.10s when I did my turbo and have never looked back. It feels a ton better, it loads the turbo down low better than 4.10s would and pulls like crazy up top...

 

Stick with 3.73, what size tire are you running? hopefully slicks

 

So.. I have decided to stick with the 3.73s.. And.. I wil be runnin slicks.. for daily driving ill be runnin 20s with 305/50s.. Also gonna be runnin caltracs as well..
