chevjayfsd,

I tried to upload a picture of the Drag 2000 screen, but I'm apparently not too good at it. So...

I did the Drag 2000 testing and used a:

3.23 gear with your setup and... got a 13.661 @ 97.5,
0-60 in 5.183, 0-100 in 13.864

3.54 gear and got a 13.612 @ 96.6, 0-60 in 5.099, 0-100 in 13.815

3.73 gear and got a 14.124 @ 98.6, 0-60 in 5.835, 0-100 in 14.327

4.10 gear and got a 14.066 @ 100.1, 0-60 in 5.675, 0-100 in 14 flat

So, as you can see - for your setup - that the 3.54 gear gives the lowest 0-60 and 1/4 mile e.t.

FYI, I used 3800 lbs. as the weight (with driver), 38% of the weight over the drive wheels, front area of 28 sq. ft. and a drag coeff. of 0.50. These are the best numbers that I have and, I believe, will suffice.

If anyone has any different opinions on the input numbers, then please feel free to say so.

I hope that this helps.

Later,
Jeff

P.S.: Incidently, your combo was doing 5297 RPM at the end of the 1/4 with the 4.10 gear and 4503 RPM w/ the 3.54 gear. All with a 2800 RPM stall convertor.
