Gentlemen, will your 5 speed handle 450 ft lbs? 3.31 geared Chevelle, would like somethig from 3.0:1+ 1st down to .85:1 in 5th,

pref 3.2, 2.2, 1.4, 1.0, .85 or something similar. Am willing to change rear drive to acheive 11-12:1 total first gear and 2500-2600 rpm cruise at 65-70 with 27.5" tire.

THXN!

Oh yes, TC discount as Jerry asks below????

The TKO 500 & 600 are supposed to handle 500 & 600 ft lbs.

There are some here that regularly hammer the hell outta theirs with more power---I'm not one of them

I think Gene might be talking about the rs500-600. I'm interested as well on pricing.

Exactly Joe. Not really interested in a TKO. Nor a hydraulic clutch. Nor in tunnel mods. Just want those "diggin' gears back and as the car runs 2000 miles a year on the interstate, even the 3.31s could stand to be knocked down.

Cant run it down below 2200 rpms though, too much cam.

Boy, it looks like we missed the "special sale" i saw in another forum . over on Jan1.

Gene, I always meant to ask you about the 5 speed you ran - didnt like it?

My friend has a 68 GTO, and he's looking at manual trans's. He currently has a 4.10 rear, but has another complete 3.08 posi rear laying around. I figured the DN/Richmond 5 speed would work good with the 3.08???

I broke it twice( not from shifting!), and it shifted really notchy. Although it did handle 7000 powershifts, unlike a TKO. THis was a beefy road race version. Loud too.

It'll work mint with a 3.08. A member here is using it behind a 9000 rpm SBC. I know it'll handle that kind of RPM. Esp with the precision custom install/build Adam has going on; i.e, he'll have better alignment for those uber R shift, and hopefully a shorter throw clutch pedal.

Part of my frustration is that launching a clutch car, with this weight and an HP based mill, is just not a fun thing. Parts break much too often. I'm out of time and money screwing with dropping trannies. Planning on reducing the mechanical load by deepening the rear gear set to 3.90/4.30, but Old Red digs his touring so.... no trailer is allowed!:cool:


BTW, I **thought** a TKO 600 would be the ticket, with the .82 OD, and sticking with the 3.31 gearset. I dont shift at 7 anymore, so 6500 ish. But if it feels like that racthety Richmond, I'd rather not. Esp not for that kind of dough.

Com'on Keisler's ; this old fart wants to buy a US made, German -named piece of precision machinery!

I'll call once the old box is out and the flywheel is being thinned out and balanced. I *really* dont think I want the 67 Muncie back in there for now.

Wonder if they even have shelf stock avail? I emailed them a form with Old Red's specs and stuff over two weeks ago and havent heard a peep.

800-404-9636!

Gentlemen,

Sorry for the delay, I haven't been on here in a while as you can tell. Will the RS handle 450 lb ft? All day long.

We have already been selling this line under the T45RS designation for 3 years. The RS name is the next evolution of that line introducing our all new tail housing and available 2.80 close ratio first gear. The power ratings and ratios are as follows:

RS400= 400 lb ft rated with 1-1/16" 10 spline input shaft and 3.37 1.99 1.33 1.00 .67 ratios.

RS500= 500 lb ft rated with 1-1/8" 26 spline input shaft and same ratios.

RS600= 600 lb ft rated with same input as 500 but with close ratio 2.80 first gear.

The input shaft clutching teeth have been torque tested to over 5000 lb ft with NO twisting or signs of failure.

The great part is no tunnel cutting is required for the RS and factory shifter position is standard. I have attached some photos for comparison of the Tremec TKO case vs the Keisler RS case. For those unfamiliar with the Tremec TKO line, it will be the one that has the boxy top and gold cover plate.

The year end sale is still going through the 14th so you haven't missed out yet!

My trouble is the .67 OD is too deep. Dont really want to swap out a mint set of 3.31s.

I think the dissadvantages of the TKO are a bit overstated. I did shift mine at ~67700, speed-shifting mind you, and it did so with no issue at all. Doesnt feel notchy to me at all, just feels "modern", not sloppy like a Muncie. Only complaint I have is the finiky 2-3rd shift, which I cant rememeber when I last missed that.

Overall, its a proven trans. We know its short comings, but you dont read about any of them blowing-up.

Wow, your mill really spins high!!! :D :D

Anyone know if Keisler plans to release a RS series with a shallow OD, say like a really nice .75:1?? Personally, having studied the math on this, I think most of us Chevelle owners with 90%+ street cars want an OD in the .75 range. I think the .6x is sooo deep and .8x is so shallow that either is always a compromise.

I totally see why some opt for the T56 Magnum, you get both!

Future plans will include a road race version with a .85 but nothing in the .7X range.

Thanks for the reply Jeff. I notice a lot of the 5 speed offerings have the .82 - .85 OD - can you tell me what the background there is? Is this a higher volume market somewhere demanding this or is this simply the ratio that works math wise with the gear sets in play?

The reason I ask is that a lot of us here want final drive ratios between 2.5 and 2.7 (mimicing the 2.56 and 2.73 ratio axle gears) - the .67 and the .85 are either a bit a high or a bit low for guys with the most popular 3.31 - 3.73 gears. Ya, I know some make them work... anyway, just curious. :)

Doesnt feel notchy to me at all, just feels "modern", not sloppy like a Muncie.

Vin, with a good shifter Muncie's arent sloppy. Maybe its the gate vs a rail shifter thta gives that impression , or the original oem sloparse shifter.

Anyway Vin, this old 138 has not been hacked, and I am not hacking it for gear ratios. No tunnel mods allowed. The car is way to close to original. which inclides every last piece of sheet metal.

Now if Jeff had a .82 OD, I'd be a-thinkin'! Ron is spot on, with 3.31 -3.55, a .65 OD and a cam that dosent much like 2000 rpms ( 75% of these cars), we'd be doing 90 at 2400 rpms.

Personally, the other racing boxes with .82 dont give as much in the first few gears. But why would a road racer need 3:1 1st?

Yet, a range of 3:1 to .80:1 would be mint. I'd prefer it in a four gear, but 5 would do! :)

Understood Gene.

But yeah, even 3.31's can use some OD! My 454 with an M20 and 3.31's along with 28" tires felt like it was screaming in 4th - even around town!!

a .82 with 3.31's would be sweet for sure! Even a .7 would work quite well on the highway.

There always the M22w option, but basically lose 4th gear IMO.

Vince, for sure. 99% of the car's use is open road, but unsure mill will like pushing that brick at 75mph at 2100. Takes a few ponies. Reckon 2400-2600 rpms is correct.

Dont know if its a physics issue or preferences, but the only TKO race boxes start with a 2.80, which is way too shallow for mid three series gears, imho.

But again, no TKO. Console car to boot.

Jeff, make me a 3.20:, 2.1, 1.5, 1.1, .80. and I';m in. ( i did not do any math - being facetuous!)

Until then I wonder if I can skate down the 1/4 in three forward gears, 2.98. 2.04, and 1.45. Gets Old Red to the stripe at 6800 rpms and 117 mph, which is spot on correct.

Seems like the best choice I have for now.

Jeff, any idea on the 5 gear, date wise and ratio wise? Ratios are more important than date, as long as I'll still be alive. Might simply keep the M20 in there for another year.

Units will begin shipping end of this month. The RS has been well received and due to popularity the lead time is hovering at about 45 days or so at this point.

Ratios are as follows:

RS400 1-1/16" 10 spline- 3.37 1.99 1.33 1.00 .67 o/d
RS500 1-1/8" 26 spline- 3.37 1.99 1.33 1.00 .67 o/d
RS600 1-1/8" 26 spline close ratio- 2.80 1.99 1.33 1.00 .67 o/d

All units will have the factory shifter position, carbon fiber blockers and will include the new billet pro shifter with built in stops.

If I had known about this RS coming out a bit earlier it might have saved me a bit of tunnel cutting. By the picture, it looks like it still is quite a bit higher than the muncie, just rounded off unlike the square TKO. I am thinking tunnel surgery would still be required on a 64-67

I don't know about you fellas but wouldn't a .7__ something OD gear make a lot more sense for the majority

No mods required for the RS installation. Check out these older comparison pics of the RS next to the Muncie. These pics are older and do not represent the latest tail housing design that we're rolling out this month. The new tail housing sits much lower than the stock piece shown. I have also attached a pic of the new RS with the shifter offset for the '64-'67 models.

Are your torque ratings of 400-500-600 at the flywheel, or at the rear wheels?


Can a HURST shifter stick be used with your shifting mechanism?

Jeff, thank you. Other financial priorities require me to keep the 67 M20 installed for another quarter. or two.

Will the shifter placement work with a console?

The ratings reflect flywheel torque and all will handle much higher spikes in input. Yes, the shifter stub will accept any standard two bolt style shifter handle.

Will the shifter placement work with a console?

Absolutely! Shifter position will not only be correct but the stub angle for the handle will be correct as well for a 100% factory appearing installation.
