How much stall??
 

Ok this is actually a few questions here goes;
My current setup is a 402 BBC in an '89 S-10 with a TH350 no brake 3500+ stall, truck weighs @ 2700lbs running a 9" with 4.56 gears on a set of 31" slicks. I'm getting things together to change trans setup to include a brake. My main question is this, if I put a glide in should I go with a different gear and also will I need more stall. I only run 1/8 mile where I'm from. Will I need to change alot of internal parts to stay together or will stock hold up? I've put in extra discs & clutches in the one I have sitting in my trailer but nothing more. I know I will change input to turbo. Any help appreciated. I'm on a budget here Thanks, Dave :x

Your 4.56 gears will work but I would say you would run faster with 4.88-5.38 gears depending on your HP and RPM range.
Is your stall made for a brake? If not is needs to be.

How much converter depends on where your engine makes power. What cam and RPM range do you run, and current ET?

Cam specs are gross valve lift .612/.617, [email protected] 254/262, usually leave on footbrake @ 2000-2200 rpm shift at @6200-6500. Stock oval port heads, mildly ported, Team G single plane intake w/ alky carb. Current ET is low 6.80's/ low 1.4's 60' times. Also US7race, I have a set of 5.29 gears but they're not set up at this time. I'm not sure about the converter, I doubt it's designed for a brake. I have another that may work though. Thanks, Dave

A 9" around 4500-5000 would work best, stick with a 4.56 if you plan any 1/4 mile trips.

Re: Need some info
 

If the go to a powerglide the stock parts that you don't have to replace for your application are the plants, the case, the sirvo, and the front pump, the other internal part should be upgraded.

You need a high gear hub, input shaft, 5-6 high clutches, and a dual ring servo piston. Only use the 1.76 if using a factory gear set.

Another dumb ? Is there a simple way of telling if I have 1.76 or 1.82? I may just wind up sticking with current setup. Starting to get discouraged with it anyway.

The 1.76 gear is alot bigger. Lets see, on the 1.76 gear the gears you see will come to the edge of the base on the plantetary and the 1.82 will be about an inch from the edge.
Instead of upgrading your stock powerglide you might try buying a used powerglide thats already setup. You should be able to get one, not tricked out, but that would work in your 402, from $700 to $1000 ready to go.

SHOW OFF!! :wink:

I have to do this mostly myself in order to be able to afford it. So where do I look for good reasonable parts & a list of what I need would be appreciated. I've had alot of answers on this topic and they've been all over the place on the stuff I really need to upgrade. Thanks again for the help. Dave

PTC, has some pretty good prices on any and everything you need, and they are good people to do business with, i have, and most of my friends have been running their converters for yrs.

If I was to put a brake in the TH350 I have now, would I need to change stall or gears that way? The trans I run has all good parts including an ultra bell but not a brake.

Your Stall and gears would work fine. I am not so sure you willl hook though.. That 3 speed has alot lower 1st gear than say a glide...

Thanks Jody, I'm looking into just buying a glide if I can find one reasonable. After adding up the parts I need to do my own, the price will be about the same. So how's things with you, haven't seen anyone this year since my job has kept me from racing at all. Take care, if you come up with anything let me know. Thanks, Dave

My glide has a transbrake,good input shaft and a dual ring servo and the good clutches but I think the rest is just factory stuff..1.76 planets.

3200 lb big block car so far no issues knock on wood.

I have a good line on a glide I think I'll get, so if I change to the 5.29 gears what stall would I need then?

If the motor will pull 7300/7500 rpm the 4.88 or 4.56 will work just fine for 1/4, as long as it won't run over 135mph. i run 5.43 but only run 125m mph and it crosses the line at 7300 rpm.

1/8th mile is all I run

Anybody??????
HOW MUCH STALL?????

Gears
 

I had 5:13 gears in my Vega once. It was great for the 1/8th but ran out of motor at the top end. I'd recommend it for the 1/8th.

Stall requirement is dependant more on where the engine makes power (RPM), less on what gear you run. This will get you in the ballpark.
