Final Drive Axle Ratio???

[FoMoCoSHO]

It's not a huge jump in gearing but with a big car it does make a difference.  My Marauder was a pig with OEM 3.55's.  I put 3.73's and barely noticed a difference.  Once I slapped 4.10's in it the difference was huge with everything I did, auto-x, drag, I even did a small open track session with it.  Big cars love the gear.

Right so my car comes with 3.16, well in my case, when I want to tune, shall I raise it? and is there a certain level to be able to auto-x and to do much better in a drag race?

Thanks

How will you raise the final drive?

I think the non turbo interceptors have a higher final drive so I guess if you wanted to go to all that trouble you could.

Is the 3.7 just a bored out 3.5? Honesty j have never looked into it...and does it still use the 6F55? I guess, is the swap even doable without  major fab work?

Yes, the 3.7 is a bored out 3.5. Initially it was believed that power upgrades were limited because of the thinner walls.  Now they have supercharger kits, go figure.

Here is a good article on the difference between the Two. 3.7 & 3.5.  Z  http://www.hendonpub.com/resources/article_archive/results/details?id=4650
