Gear Ratio??
Gear Ratio?? Well, I broke the ole' 10 bolt last weekend. I am saving my nickles and dimes for a 9". What kind of gear ratio are you guys running. I trapped 111.70mph on motor in the quater last time I was there. I added a 150 shot to the mix. Unfortunately I will not be able run it and know what I trap with the N2O. I am guessing around 122-125mph. I did a tire/trans/gear calculator. I shift at 6500-6600 and that would put me trapping at 129-130mph with a 3.89 gear ratio and a 26" tall tire. Final gear is 1:1. Would a 3.89 gear be too much gear or would it be all right. Just doing a little research. I only want to do this once and be done with it.
I got a buddy that runs a 402 LS2 motor, N/A with suspension, and everything else about 127 in the 1/4 on a 28" tall biasply slick and a th400, and 4.10 gear, compared to a 28" tallk drag radial it did grow where he lost like 1ish mph. He is planning on tossing 100 shot this upcoming weekend, we suspect he is going to run out of gear but we have to see his converter is ULTRA loose (can stall an easy 5500rpms)
Look at what mph your going to be running, max RPM and back off 300-500 rpms and aim for that mph. Change the gear accordingly
Oh and for your setup, you have a 26" tall tire, your not going to get the side wall flex like a 28" tire tire, even if its a slick, having lesser gear may help if you spray off the line.

just got my moser installed like a month ago. Got 3.91s and they are awesome. Track is closed for winter so I can't comment on my trap speed or anything like that. at 70mph cruising on OD im at 2500 rpm.
