Gear ratio advice

[MJmalibu]

Can't decide what ratio to go with.
My setup is 540 850hp(7500 rpm), glide about 3000 lbs and 33" tires.
I am thinking 4.56 or 4.88?or whichever ratio is close to those with a 9"
Anyone else with a similar combo? What was your ET/mph in a 1/4?

Well I used that calculator and the one on Richmond website and 4.86 seems to be the right ratio as long as I am close on my weight. How much ET would I expect to lose if I went with 4.57 and left a bit on the table by the end of the 1/4? I may put a small kit on it at some point.
