I'm about to swap my Th400 out for a Glide.. It has a transbrake, turbo splined shaft, full set of planetaries from TCI w/ 2.02 1st gear ratio, etc etc.. Everything is aftermarket besides the case basically.. The question is..

What size converter (stall size) and rear end gear are you guys running that will make it thru the 1/4 at 140+mph @ around 7400rpms.. 408ci engine with a healthy shot in the 300hp range so roughly 800-900hp. Should be a low 9 sec car.. Running a 28" Drag Radial tire..

I'd really like to keep it more of an 1/8th mile car, but would like to hit the 1/4every now and then.. What are your opinions???

Thanks,
Matt

4.10 or 4.30's and a custom 9" converter should get it done for you.

I would get with Chris at Circle D. That is what i run. I think a 4500-5000+ would be best.

Thanks for the PM reply.. I was thinking in the 3.90 to 4.11 range since I have the lower 1st gear ratio and didn't want to hit the **** out of the radials with the jug and too much gear out of the hole..

If I was running N/A or with a smaller size shot I would go big with the converter, but I think that might be too loose for a nitrous setup.. Could be wrong though..

You'll need something that will go to about 4200 on the brake I'd think to get that running right .

4.10 gear should work too. 2.02 first gear is low, most of the glides I see are 1.8, or the ones for the BIG power guys are 1.69

talk to marty chance and neal chance racing convertors he will get you hooked up. i have a billet pro mod bolt together and it is perfect and if you want to change the stall you can do it in the garage. they are kind of pricey ($3000) but wanting to go that fast you get what you pay for. mine was perfect the first time i put it in

no it wasnt nice , notice how yours is pretty and painted....... mine is in black primer. Marty and the guys at chance are awesome and hooked me up look for one on racing junk a friend of mine picked one up for 1500 the other day then call chance with the number on it he can tell you exactly how it is setup and will adjust it for your need and set it up for an ls1 crank. does your glide have and turbo spined input on it. mine has a 1.76 first gear in it and leaves great on the gun but sucks *** on the motor. it goes from a 11.5@125 on the motor to 9.74@140 on the 150s and we have similar setups from what i have read on your car. i was looking for a th400 if you wanted to do some trading.

N/A BBC, 1.80 glide, 29.5 tire at 7300 rpm, 145 ish, with a 5500 8".

Your smaller tire will raise rpm, if you can get a 9" converter to work, you will lower rpm due to less slip.
Lower 1st gear, so as mentioned harder hit, so 3.90 might be the high end of gears.
You can guess rpm using ~300 rpm per gear size. Works on both of my cars. Good luck.

Oh yea, what was original combo & numbers.

Thanks for the info! The old combo was a Th400 with a 3.50 gear and 28x10.5 slicks.. Trapping 135 with a little room to go rpm wise.. That was with a 100 shot and 10.00 E.T. off the footbrake with minimal tuning..

I think with the glide it will go high 9's on the same 100 shot.. I have also removed about 100lbs maybe a little more from the car and swapped to 2" headers and bullet mufflers so should be a slight HP increase as well..

lol I know what you mean.. If I ever step it up to the next level I would consider going with a Chance converter, but right now its only a test n tune type car for me.

My glide does have the turbo splined shaft in it.. I am anxious to see how teh 2.02 gear set is gonna work out on both the motor and the jug. I was running 10.90s N/A and going 10.00's on a 100 shot. I think it had 9.80s in it with the 100 shot and more seat time/tuning time. That was the only time I had ran the 1/4 with the car and only the 3rd time out with it period. I want to go LOW 9's with the 300 pills this go around.. Maybe with the new exhaust setup, the 100lb weight reduction, better tuning, the transbrake, and some practice I can get it down there..

We have a 2950# car with a sbc that has a 6,200 stall, we shift it at 8,200 it runs 9.60's right about 140 mph 1.34 60ft with a glide, think it has the 2.0 gear, 31" tire and 5.13 gear, perfect for motor passes, but were at 8,200 in the lights so we can't spray it till it gets either a 33" tire or we swap the gears.

You're going to slow down in the 60ft, but you'll notice the difference especially after the 1/8th mile. Personally I don't think it is worth it to swap to a new trans when you only plan to go 9's I think the TH400 will work better especially if you're going to go 1/8th mile, the extra 1st gear is really going to help the car get out hard.

Well the Th400 probably would be better in some ways, but I believe there are pro's and con's of both. The extra hp gained from using the Glide is always good as well as the weight savings.. This car still weighs well over 3,000lbs as it is. The car had a lazy *** 60ft before pulling 1.60's on motor!! lol and a 1.43 on the 100 shot. I believe with a glide and the 2.02 1st gear with a 4.10 rear gear that it won't change very much. The biggest part is gonna be the converter this time around probably..

Converter will make or break the combo for sure.

Good luck !

I have an Edge Pro Billet, they are great converters and not too pricey. You can't beat the customer service either.

Right now I am running 3:55 gears with 28's and a glide. The 3:55's aren't quite enough so I'm stepping up to 4:10's. I was spraying a single DP kit and making 711 rwhp but I had traction problems so I added a plate kit, I'm gonna launch it with 150 (plate) and then hit the DP jetted for another 250. It should be a little over 800 rwhp and everyone has told me that 4:10 will be perfect for going though the traps around 7200 RPM's

Seriously, give Edge a call, they will build a converter for whatever you want to do. My Edge converter was already in my car when I bought it, I sent it back to be re-stalled and they put the warrenty in my name, sent me a shirt, stickers, etc. They didn't charge me very much at all to do it either! I think the tech guy's name is Andre, give him a call and tell him Josh Shumway sent ya.

I appreciate all the help from you guys! I pulle the trans last night and I'm pulling the glide from the other car tonight.. I'm gonna send the converter to PTC and see what kind of magic they can work on it. I like to deal with the local shops if I can and PTC is only about 30-40 minutes from me.. If they can build a custom converter for my friend Ken Rainwater then I "think" they can handle a little ol 9 sec car..

Thats almost exactly what I'm doing.. I have a Speedtech Diffuser 2stage plate system.. I'm planning to hit it with 150 out of the hole (maybe more if the radials can stand it) and then another 150-200hp worth on out there..
