flamed 98 gt said:
Yep that is what I have now the 2.73. Will there be any noticable difference??? (J/K)
yeah thats my old stock...you will notice an HUGE difference between those ratios like 2:73-3:73/4:10's.....

This is on my 90. Cobra upper and lower intake, bbk 70mm throttle body, long tube headers, bbk o/r h-pipe, 2 chamber flows with dumps, tfs stage 1 cam, ported 351w heads with a valve job. Going to have it dyno tuned soon any idea of what it would make. I would like to see it hit about 300 rwhp.

Thats kinda wack because I ran a 12.23 with very similar mods on street tires.... only I had autocross suspension.... and just different branded parts....
 
with 4.10s and a t5 what kind of mph would you be at around 5500 rpms? i know it depends on tire size and all but just on average what mph have you guys seen in 4th gear. i am thinking of switching from 3.55s to 4.10s.

With the stock 17-in wheels and 245/45-17 tires. I'm right at around 100mph at 5500 rpms.

As for my setup:
Stock shortblock
Steen Racing Stage 2 Heads w ModMax oversized valves
Comp Cams XE270AH Cams
Comp cams Beehive springs, Titanium retainers
Fenderwell CAI, Stock MAF
FRPP 70mm TB, C&L Plenum
Mac LT Headers, Mac Off-road H-pipe w/ Magnaflow hi-flow Cats welded
4.10 gears in the pumpkin
Runs 12.7-12.8 all day
 
do you have a 1998? or do you have a fox, if you have an 8.8 there is o need for a 9 inch, the 8.8 is good for what you will want and richmond for the brand
 
I have 3.73's 5 speed and I run about 3K at 80 MPH. They are awesome I love the gearing and I dont think I would need to step up to 4.10's that to much gear IMO.


And I still get 18MPG on the interstate at 80 MPH
 
3-73's here in a 5 speed, i had 4-10's in a automatic stang i used to own
Thats the ticket... 3.73 manual.. 4.10 auto.. If it is mostly a street car. You will like it..

I have heard the same thing. But others will swear by 4.10's in a manual trans car too. Its all preference and just weather you do highway driving or not. I wouldnt get 4.10's if I was doing any long distance highway driving I dont even like my 3.73's on the 8 hour trip to Indianapolis.


But I have never drivin a car with 4.10's so I dont know what its like on the street
