You lose the power by going to a lower gear because the gears are spinning so fast they are acting as a prop in the oil thus they create bubbles. Atleast this is what I think...
Also by going to a Ford 9" from a GM 10 bolt you lose power because going from a 2 letter word to a 4 letter word doubles the surface area letting the power spread out further, thus lowering the peak...

Lulz...
On a more serious note.

"GM's design is more efficient than Ford's. A 12-bolt's pinion is 1.50 inches below the ring-gear centerline compared to Ford's 2.25 inches. For the 12-bolt, this results in a 3-1/2-percent-less horsepower drop through friction reduction and lower gear lubricant temperatures. The 12-bolt is also around 30 pounds lighter than the 9-inch."

Bite I could not get the website to work, maybe because I'm on google chrome. All I can tell you is the change from 4.10 to 3.90 was a noticeable seat of the pants difference that showed up greatly at the track. Like I said the program we used on the race team I worked for the 3.42 was starting to be better above 80 and was alot better by 125. I have more faith in that software that we used to gear our hewland gearboxes vs internet download.
This guy in this thread also had the same thinking as you. Is everyone else wrong in the thread too? Many of them have n/a motors that run 4.10's and are faster. They must be doing it all wrong.

I also saw another thread where you chimed in and said you did a few things after the swap to 3.90's and u picked up mph. So that wasn't mentioned in this thread either. Go onto YB and ask the very same question. You'll get the same answer as what I'm trying to explain to you.
But now that I think about it...I'm wasting my time/effort trying to educate you so keep your 3.90's. You'll never open your mind and try to understand the math behind it. I'm done.

HiO your car may be a 126 car but your credibility gets lower when you say ignorant **** like you have in this thread.

Yea yea yea....blah blah blah
Bite I never got a true back to back after the 4.10 to 3.90 gear swap. The only real change was my drag wheels with dr's when I went back other than the gear. But still not a back to back. I can to you the back to back of the 3.42 to 4.10 was .1-.15 and 1mph. Same wheels /tires although a different but comparable day. Not as great a change as everyone thinks. I'm sure gear works good for your 4.6, you need to multiply all the tq you can.
As a side note. I still have all my inner bumbers, alot of fbody guys remove them, pm those guys if you have a problem with saftey. Doors bars are still there and the main chassis have never been cut on. Just bolt-on parts and a careful selection of how I do it and the parts I buy or make. I've had lots of guys pm me about what and how I've got the car that light. ...remember, if I were to wreck it there is also less weight to stop on impact or if someone were to hit me it's less weight to move. Bet you did'nt think of that angle.
Bayarea....your car would'nt run like it does w/o h/c. I don't know why anyone would blame my #'s on weight alone. If you want add 400lb back to my car in your head if it makes you feel better. We've all chose our mods here. Keep a open mind and live with it.
