Gear ratio Question
 

I need a recomendation on which gears to put in the Demon.
Last time out with the car I was shifting at 6800 rpm, but crossing the line at around 6200rpm.
340, 13-1comp, .530 solid cam,850 holley,
4500 converter, 4:10 gears, 27.8"tires (325x50x15's)
Should I go with the 4:88's, the 4:56's or stay with the 4:10's.
I have all three. the 4:10's are on a spool and the other's are limited slip.
Suggestions,comments? :-k

I believe you go through the traps + 200 rpm per gear size up .

Let's see, that's
4:11= 6200rpm
4:30= 6400rpm
4:56= 6600rpm
4:88= 6800rpm
4:88 work out to be close that way also. :-k

Do you know where your power band, curve is?

Are you pulling hard at those rpm's? :-k

I ran the combo through Desktop dyno2000 and the hp should peak around 6500.
It didn't feel like it dropped any power when I ran it all the way to the rev limmiter at 7000. I was real slow pulling the shifter on that one. But that's the 12.60 run.
