I am thinking of putting Moser 4:10 on my 6 speed trans am. what kind of RPM are you getting at 70-80 mph? trying not to waste too much gas.

I had 4.56 gears, .54 6th, 26.5" tall tires, and pulled about 2200 RPM at 70 mph.
The problem wasn't 6th gear or highway. It was the fact 1st and 2nd gear were totally useless. You could start out in 3rd gear without any problem. I now have 3.73 gears with the same trans and it runs like a bat out of hell now.

9 bolt??? I think you mean 9 inch. When it comes to strength of rear ends a 9 inch Ford or a Dana 60 are much stronger than a 12 bolt Chevy. It all depends on what you are going to do with the car. I have broken a few 12 bolts in my day so I'm not a big fan of them. On the other hand a Dana 60 and a 9 inch Ford are what you would call bullet proof.

I run a 12 bolt with a 6spd and if its set up correctly they are plenty strong with out the additional weight. I have 3.73 gears but will be going to 4.10 soon. IMO the 3.73 aren't quite enough but I have a monster cam and run 27 inch tall tires at the track. On the street with toyo drag radials I can't hook hardly at all already.
