4.30 vs 4.56 gear

Im not sure.

I run on the street grudge race.

The speedo is the only non functional gauge in my car.....

I estimate on the HWY im doing 50 mph at 3-3,300 rpm.

My car is NOT fast (mph) but it is STUIPD QUICK. (ET)

i know im not helping much but i would definitely not worry about 4.56.

Im looking at a substantial increase in HP soon and i plan to reduce my rear gear by a lot. Hopefully i can keep my ET about the same but gain some more driveability.

You don’t think 4.56 is much of a step up. I like to cruise mine to worth on ends or twice a month. And trailer if it to race. Currently with a 4.30. And a tire 275 45 18 rear.(looks tiny under mini tub) I’m going 55mph at just about 3000-3300 rpm. And it’s a 20 mile cruise each way Car tachs out at 6k. Could go a bit more. But play it safe.
