i've been away because i thought this thread had run it's course.

First off let me say this. The fact that I am a relative novice at automotive work doesn't mean that I have no technical experience. I work in a technical field and do a lot of design and fabrication work. To begin with I am say "technically minded"

I had never broken down an engine to the block to change heads before I tried it then I had. Was that easy? Yes it was. Was it frustrating at times? Terribly so. I have a press in my shop so that won't be a problem. I can read the contact patterns so that should be fine. the only tool I don't own is the inch pound torque wrench(I have a click type) I would rather use a dial type torque wrench but suppose a bar type would work.

At the end of the day I'm going to do this myself. It isn't my daily driver it's just a toy. I want to do it myself not only to save 500 bucks(which is the cheapest I've found here) but also for my own edification to know I did and frankly I enjoy this sort of stuff. It's going to have to wait until after I build the 88 though because there's only room in the garage for 1...

it sounds like you have enough tech knowledge to get you in trouble. I used to work as a heavy line mech, mainly removing engines from old crap cars and rebuilding them cheaply. I've rebuilt dozens of engines from 4 cylinder overhead cam to good old chevy v8's to ancient and massive GMC v6's. I still wouldn't mess with a rear end. But if you do, I hope you post the results.

we have an 05 gt with the stock 3.23 gears in it and we want to change to 4.10 gears but heres my question my wife drives the car back and forth to work not more than 5 mile one way and its 45 miles and hour and 35 miles and hour most of the way. But the place that Im getting the gears from {American muscle} says that it will actually increase the fuel mileage at those speeds or in town drive and i want to know if that is true or not. Because me and my wife dont want to lose our gas mileage really bad by changing the gears beacause if we are we just will not do it. and a second question with the mods that I already have like a JLT CAI and 62mm throttle body and a catt delete x pipe and a sct tuner with a 93 octane race tune in the car what kind of times should i be running when i change the gears because the best i got now is a 13.75 at 101 mph and I really want to be in the 12's or faster if thats at all possible... any help with these question would be greatly appreciated...

if you get better gas mileage at lower speeds, it will simply be because you use 5th gear more and your overall rpm at say, 45mph, will be lower in 5th gear with 4.10's than it would be in 4th with your current gears. Highway mileage will suffer and you will be running at higher rpms at highway speeds.

oh by the way it's an automatic

not sure if you decided but here is a deal if you go 4.10's
