I know that there is a lot of questions on rear end gears so heres another one. Im running a 4/10 mile high bank track dirt of course i have a powerglide tranny should the rear end gear be about a 5.83(running glide in high 1.1)the tires are the IMCA McClearys also would that gear also work for a 3/8 track running glide in low.
Thanks Eddie

You should do O.K. at both places with a 5.83 final. Is your final the 5.83? I have ran 3\8ths mile with that gear and it worked great. The .4 track might be a snitch high but you may find it works alright.

I would tend to agree. You have good gears for the tracks you will be running. In fact, that is pretty much exactly what you want for those applications.

I entered your info into the MPH calculator in the tool box, and this is what I found. At 5.83 with the tires you have(13.2in radius you will be running 74MPH @ 5500rpms. That seems almost perfect for a .4 if you ask me. I personally like to keep the rpms about here. I would rather do this than build motors all the time because I ran the heck out of them @7000 or something. We have to keep cost to a minimum. Think of all the other stuff you could use that money for.

depending on what you want to turn rpm wise that might be alright on the 4/10 most of the imca stock cars around here turn 60-620 but they also turn about 65-7000 rpm as for running the 583 in low thats going to put oyu in the 10 for a final thats way out of the ball part in my opinion you would be better off just running the same at bolth tracks instead of low

Racer17j the glide is going to be ran in high gear which will make the final 5.83 the low gear in the glide is 1.82.

ok so your hi is 1. and a 5.83 ring and pinion if you ran low thats 1.82x 5.83=10.61

Flatlander is right on. Lugging a motor will kill it! Its for racin' not grocery gettin'. I race on 3 different 3/8 mile track and most everybody runs between 6.20's and 6.50's. Some more than that. Yes, thats the small IMCA tires. Thats good for 6800-7500 RPM most nites. After I find out gearing for a new track, I take the tach out, its worthless most of the time anyway, just recording lighting up the tires on one lap. When deciding on gearing, think about your car "comes on" at and how it compares to other cars coming out of the corners, but don't mistake chassis shortfalls for lack of HP. just me ramblin' see ya'

hey flatlander it's kinda funny how us iowa boys and our low rpm go down south every spring and take all the money home lol anyway with the rules we run the cams we can use fall off after around 6500 so turning 7000 would hurt me alot more than it would help. generaly in the hobby class around here we turn 6.0 on a 1/2 620 on a 4/10 and 633 on 3/8 then 650 on 1/4s

we don't run anything like that up here 95 % are imca if i rember right the last 4-5 years at talladega short track the winner in imca stock was from iowa and alot of guys from here go down to texas and run the early spring shows and do real good

Yeah that Flatlander is absolutly right! I'm from the North (just above Knoxville) and it's not unheard of the see guys running 6:50 final drive at the Gap (4/10th very high banks) I like the 6:20 with my 355 and get down to 5:83 when the 406 decides to run. I've been thinking about setting up a 5:67 to see what would happen???? That 406 has got a load of low end torque and I just wonder------

OK you high HP guys, listen to what I have to put up with here in NY. We can only run cast iron intakes, 2bl stock carbs, stock exhaust manifolds, no aluminum pulleys and a $300 claimer....need I say more. Here, and I'm sure in most "street stock" divisions, we are not turning a lot of horses and our motors are truly stock. Much more than 5500 rpm's would kill us quickly. I guess the souths vision of stock is basiclly "run what ya brung". Anyway, good luck to all this season and keep those revs down.

right on ny we are the same way here in iowa i could never figure out how they can call a class pure stock and run 10 tires last time i checked nothing came stock with tires that big lol i guess they think it will keep cost down by having to run used tires

Where ya live and where ya race kinda dictates what ya bring to the show-don't it? Entry level cars at Bulls gap were re-invented last season because of how expensive the classes had become. If I brought a 2000 entry level car to Iowa I'd probably have to run with the limited lates. If you had brought your entry level car ro Tennessee you would have better to have left it on the trailer.
The new class has -in one year--gotten way out of hand. The track doesn't tech them and the guys want to win-so what happens? 11:1 motors with bowtie intakes and 750 holleys. Monster camshafts and light clutches and flywheels. Is that the racers fault----is it the fault of the track? That's just the way it is.
I didn't want to spend $12k building a dirt car----I just wanted to get off the asphalt before I got too dam old to give the dirt a try. So to be competive--I built what the other guys were running. If there had been a less costly division to start in---I'd have been right there.
I'm not saying we're better that you. Or smarter or dumber--just that we've different rules to play by. Three of our top drivers went to MCS for the world championship and none made the field----Ohio rules had unlimited steel motors and ran 8" tires--we got out handled or out hp'd or out driven.
Flatlander-I didn't know Scenic was opened? I thought Carson had bought the place and closed it down. I've run at Cleveland--that's a fun track---just got some wierd rules-
Come up to Volunteer for one of our Tuesday night shows-I think there's 3 or 4 on the schedule. I promise we'll treat ya like yer family!

i think thats paert of the reason why we have so many racers around here we keep the rules so they are as cost effective as possilbe heck even out late models have to run a spec motor

thats just the thing we can run our cars at any track in the area with very little changes we have at least 3 tracks running with in a 100 mile radius on friday sat and sun nites . ilke saturday we have 30 hobby stcok 35 miles south of us they run imca and they get 45-80 some nites and then 45 miles north they get 25-30 and about the only differece in any or the rules are tire rules and plastic noses and the tires are all street tires. i myself don't run the plastic nose so i can run at any track in the state in the hobby class

Flatlander-I ran at Newport once last year and wound up in the wall. I've ran there in years past tho--that's the fastest paved track I've ever been on! I called Kingsport Speedway home for 4 or 5 years --but ran at LPIR most every Saturday night till they went ARA. So------could have been me (you race--you know what it's like meeting fans/spectators at the track)

actually it was Kingsport I got newport on the brain today for some reason I liked the racing at kingsport it looked pretty quick to me I ran asphalt in the early 70"s really got bored with it I always liked dirt better but just a preference I just felt dirt was a little more fun where I grew up the paved track was a high banked 1/2 and all the dirt were 1/4 and 3/8 and I was sideways on the pavement most of the time anyway so the old man said it'd be cheaper on dirt and a lot easier on the body I just can't beleive how hard you can hit on pavemaent don't get me wrong you can on dirt also but I swear I slid faster that I ran sometimes well any way we'll be up in about a month to watch anyway I always like to see what I'm up against I 'll try to email the week I'm coming and maybe we can meet and talk Good luck The Flatlander
