What is everyone using for as a gear ratio

(1/5) > >>

grapro:
Looking at purchasing a complete center section from Strange and have used all the calculators and have a bit of confusion. don't want to rev too high and been talking to some of the local racers and debating between a 3.89 and a 4.11. Just running a small block 355 alcohol injected with aspirations of maybe some nitro someday and wondering what is common for a ratio.

Paul New:
What HP level, MPH, tire size, and RPM's are you going to spin the engine

when I ran injected alky 8.20-40's in my FED I ran 4.30's and 31x11 tire

dreracecar:
Injected SB generaly runs NE2 (8.60 @ 155)  but still more info is needed
Are you running a trans? what gearing is in the trans? how much does the car weigh with you in it? where is the listed "sweet spot" on the cam? 1/8 or 1/4 mile? what tire? most converters slip 10/15mph on the top end. The difference between gear changes is around 200rpm
I would not go taller than 4.30"s

I am running a glide with a 1.76 and have a 30 x 10 tire. Motor is fully balanced and printed 355 with  built aluminum heads used to run it at 7000rpm in my truck  but not that crazy anymore and going to alcohol with it now. would like to keep the rpms to 6000 for starters, 5000 stall in convertor has a brake but not sure if I will use it at the beginning, not quite sure of the car weight but a pretty basic fed. I am new to all of this just hoping to find a happy medium in the gears, will buy a pro gear set with large stem pro gear pinion, parts are all too close to my privates to buy brown paper gears as I already had cancer down there and don't want to lose them now to cheap parts. But not quite sure of which set to start with. Novice to all of this.

We run a powerglide with a 1.69 first gear.
4.30 gear in a 12 bolt. 
Goodyear 2585 31x12
I use to leave off of a transbreak and 2step but found that my 60' times are way better when I swap feet at first sight of amber. 1.07 - 60'
