What will these mods do?

[esandes]

In my neverending persuit to perfect my ride to how I exactly want it, I'd like to know what I can expect by swapping gears to 4.10 and swapping the stock pistons to flat tops?

I'm unhappy about my low end torque and I think the 4.10s will help with that. It seems that I have to be over 4000 RPM to get the car going very fast. I went with 3.73 because some people here said that it makes 1st gear useless.

The flat tops will bump the CR from 9:1 to 10.3:1 or so. So that there will give me some extra HP. I'm guessing TQ will go up too.

Also, can you make a good guess how my curves will look with these mods please? Will both curves just go up? Will I end up with a dip at the higher RPMs?
