BTW: thanks Rench for the info.. mine will be in soon as I make up my mind now.. 4.10's or 3.73's.. witch way to go..??? lol

if is going to happen soon .. very soon .. next week or two at the latest.. [sm=gears.gif]

 

Well i got 3.73 put in my auto yesterday, and its a difference you can feel. Im going to the track later today and see what kind of difference i get. At 80 my rpm are at 2600. With 4:10 i wouold be at 3000, thats a little to high for me

 

Actually with 4.10's in mine I am at about 2800RPM at 80MPH

Still getting 19MPG City and Highway driving mixed.

 

I am going with 4.10's after talking with my "tune guy" also doing a C&L CAI and a SCT tuner..

what he likes the best .. after all parts installed and a "tune"... I should get 300 true RWHP .. as per him they come stock at about 270 -280 ...RWHP...

plus it will take off like a ( jack wabbit )... <--Elmer Fudd sound effect... lol


from a stop... next week everything will be on and done.... oh yeah.. wOOt...!!!

I think you will be happier with the 4.10's. Go with it........................................

 

Great input here.... thanks. But , can anyone give me a ballpark figure of cost (I'm not equipt to DIY)

 

$200-$300 depending on the shop....
