How much will gears help my 60ft?

[POWER302]

I have 3.27 gears and am running 26x10.5 ET.Streets.. With launching at about 4000 rpm my best 60ft is a 1.80.. I will be going to 4.10s here soon.. How much should my 60fts drop from the gear swap and using the same launch rpm? Is it possible to get in the 1.6's ?

Thanks

with 102 traps I'm assuming you are puting out 230~250hp...
no reason that car wil not see low 1.7 60' times... maybe a 1.6 if the track hooks well.
