I don't know what forum to post this in so... Trying to guesstimate what gears are in the notch I just got (without actually checking!). 93 5.0 with 5 speed. Stock size 16" tires on ponys. At 70 mph I was running about 1900 RPM give or take. Any guess
Most came with 3.27 at best i think rpm and mph seems right.
If your running a 225/55/16 tire, they are close to being 25 3/4" tall. Using this formula: rear gear x 336 x trans ratio gear (5th in your example) x speed and then dividing that by tire height we arrive at a 3.08 gear.Originally Posted by Cam99
Here's what it looks like... 3.08 x 336 x .68 x 70 divided by 25.75" =1913 rpm
Tires by different manufacturers will vary slightly in height and the calculator is intended only as an approximate guide.

Yup that the other gear ratio they came with.

what are you plans Cam? Post up some pics. I'll have to come by and take a look at that one some day.
It's going to be mostly a strip car, but still streetable. I'm going to de-mod the mach a little and just leave it as a cruiser. I'll get some pics up shortly. Stop out anytime, I wouldn't mind seeing your new ride as wellwhat are you plans Cam? Post up some pics. I'll have to come by and take a look at that one some day.
I might have a set of 3.27 soon. You'll probably want something bigger than that, though ??? !!! LMK.It's going to be mostly a strip car, but still streetable.

Yeah I'm probably going with 3.55 or 3.73 depending on what route I take with the car. Thanks though.

WOW. They felt like the stockers which is going to have to change. Thanks for the info!
If you want to know what gears are in the car without taking them apart, just jack the back up, turn the tire one full revolution and count how many revolutions the driveshaft makes.
1tire rev and 2 3/4 driveshaft revolutions = 2.73 gears
" " " " 3 " " = 3.08 gears
" " " " 3 1/2 " " = 3.55 gears
" " " " 3 3/4 " " = 3.73 gears
I'll have to stop too Cam, now that you moved on up to the east side--a delux apartment in the sky. Melcroftians were my mortal enemy growing up lol.

Hell, I don't have a clue where he lives. I was just gonna roar up and down 381/711 until someone stepped out in front of me with a shotgun.
Or just look on the Tag of the pumpkin

If you roar up and down 711/381 you would blend in. If you want to stop out I live on the road right next to G&D market ( which is on 711/381). Last house on the right.Hell, I don't have a clue where he lives. I was just gonna roar up and down 381/711 until someone stepped out in front of me with a shotgun.
You might start a turf war if you come to my house...Melcroftians never forget their enemies!!!! Stop out anytime. My phone numbers are still all the same.
I think everybody here forgot about the desert gear. Thats what was in mine. Acted the same as his. Ditched the 2:73's in favor of 3:73's. Best mod yet. Well, as of two weeks ago. I should fire it up Saturday if all goes right.
