yes i think you will see a 1/4 mile gain. as far as "being out of breath" at the end of the 1/4...that depends on how high your car makes power and what your redline is. i have 3.73 and my car is DEFINETLY out of breath, but i can only rev the engine to about 5200-5400 rpms(about 200 to 400 OVER redline stock). you'll probaly be ok since your car has a 350 vs my 305.

 

Depends on how much power your making, if your making close to 300hp you will probably be outa revs before the trap.
as far as shifting goes, do a few runs and see how it acts when you shift before, at and maybe a wee bit over redline.
I think you can simply pickup a new speedo sensor for your trans and dif ratio from a GM dealer.. I think??
I hope so, i havent gotten my speedo fixed yet

 

On August 24th, I was sitting in the 5000 RPM range of third gear when passing through the traps at 100 MPH.

I have 3.73's and a 305 L69 engine.

They will tell you the right gears for your speedo in the tech articles here on thirdgen. That is where I got the information on mine. Check it out.
