005 GT said:

for those of you that have installed the 4:10 gears with a manual tranny.....how do the gears perform on a long trip......300 to 1000 miles?
im wanting to install these gears but am hesitate. how much would they change RPMs and gas mileage? thanks for any input guys.........

RPM and mileage difference is minimal. There are many threads on this with details. I get about 19 MPG mixed driving. I would do it over again. Good luck!

how much quicker is your acceleration with those??? big difference or small difference??

4.10's .....excellent

On a long trip in 5th cruising down a highway there is not a ton of difference between the 3.55's and 4.10's ....I noticed a couple of hundred rpm extra...no big sweat....But....What a hole shot difference....4.10's are awesome, especially when you have cold air and a tune program on board!:happyhapp

Watch the rev limiter...you run out of 1'st and 2nd really quick with these Mod Motors....good hunting.

Cheers Paul

im for sure going with the 4:10s stoenr, but not until spring. im buying KJ's CAI and X pipe. then ordering the FRPP shorty headers and gears from Champion Ford in northern Kentucky. that dealership is the only FRPP dealer around this area. and i'll let them do the install of the headers and gears at the same time. i'll sure let everyone know how things work out. this car is TOO much fun. lol
