Anybody running an A4 and 4.30 or 4.10 gears with 27" tire?

Do you think my 1/4 mile time will suffer going to one of these gears.
I run 12.25 @ 108 mph 27" tire 1.68 60' 3.73 gears 3200 stall

I'm ordering a 9" and would like to run a lower gear, for the next motor, but I can only do one at a time. car is 98% strip
thanks for the help

You will be fine with a 4.10 You shouldnt have to worry with your gearing until 120mph or so.

thanks guys,
I think 4.10 is what it looks like will be better for me, after searching around on the web, looking at other set ups. even when I build the next motor which will be a 383 or 427, approx 550hp
for some reason I was set on 4.30's, My goal is to one day pick the front wheels an inch or so off the ground and run a low 11. but I see lots of people doing it with 4.10's

I used to pull tires on 3.23's. I think 4.30 is a bit much

pull'em up with no power adders and a low gear, wow impressive!!!
I have hope, maybe I should debate 3.89 and 4.10
interesting
