Anyone have a Keisler RS 500/600?
#41
RS400= 1-1/16" Ford style 10 spline input shaft
RS500= 1-1/8" GM "fine" 26 spline input shaft
The 500's input shaft is stronger allowing for the added 100 lb-ft torque capacity.

Based on your info the RS400 will be all you need. The only difference between the two is the input shaft and spline count.
RS400= 1-1/16" Ford style 10 spline input shaft
RS500= 1-1/8" GM "fine" 26 spline input shaft
The 500's input shaft is stronger allowing for the added 100 lb-ft torque capacity.

With a big block it would for sure but with a lower torque 327 I prefer the lower gear to get the engine up on it's legs so to speak. Realistically, at 5000 rpms there's only a 5-7 mph gap between the 3.37 and 2.80 first gear.

I'm going to be going with the RS500, as my rear gears are 2.87

L79 and keisler 400 vs 500
Keislerjeff , thanks for the response. I had a tremec 600 with a ls2 engine in a 67 restomod i made .it was great, this car is a matching number but i love driving it. I was wondering about the launch with the 3:70 reargear and the different gearing between the 400 and the 500 close ratio 1st and second gears. Should my launch wi th the 3:70 and the 400's 3.37 be rapid, smooth and not need to slip , or should i buy the 500 with the 2:80 ratio?

Keisler,
As was asked earlier, I'm also curious how you arrive at the stated torque limits for each. What does your test consist of? Would an engine that occasionaly flashes to 435TQ kill the RS400? Also, if one wants to upgrade from the 400 to a 500 due to engine upgrades what would it take, just the different shaft? Would you sell this to customers?
Thanks,
Bryan

I refer guys to this video on youtube quite frequently. This guy is running the original stock T45 in his car. Check it out!

Drifting
I had to wait my RS600 about an year. And i must say i hated it, and i am sure it came thru via my emails to Keisler. But i have to admit at folks at Keisler handle it really well. I got fast and prompt answers to all my emails. Customer service was really good.
I have no idea to this day is it possible to install under the car with engine on but i could not do it. Not wiht hoist or on the floor. So i took the engine out.
There was one flaw on the main case. The mounting holes for the bellhousing side were about 1/8" offset. So when i mate the transmission and bellhousing ( new from keisler ) i could not install the bolts. I had to grind the mounting tab holes to get the holes in line with the bellhousing.
Driving quality was improved about 1000 times better compared my orginal 3 speed... wich was no suprise. But still beats every munchie, dough nash 5speed or ZF6 wich i have had during the years. Allmost as good as T56 wich i had in my 63.
And the fifth, what a pleasure to drive with 3.7 gear i have

Just Verifying
Very good thread guys. This looks to be a great forum
I just wanted to verify what I've read. I have a 454 HO crate engine ready to install in a 1974. It has the stock 3.36 rear. Kiesler recommended the TKO 600 is that the consensus here or he RS 600.
Also if the engine is out is removing the cross member a must.

OK that would settle that. The response from Keisler was that with the 3.36 rear end ratio the 5th gear in TKO 600 would provide the best performance and that is what I am gathering from this thread.
Thanks for the input

If your car originally had a manual transmission the cross member is non-removable, if automatic than the crossmember is removable. It is my understanding that to remove the transmission with the cross member in place one must unbolt the motor mounts and move the engine forward an inch or two to get clearance to get the trans out. If your motor is already out I think you should be able to get the trans out without removing the cross member. There are also flanges available to convert your non-removeable cross member into a removeable cross member.

You might also consider getting the Keisler SS700 transmission which I think is generally regarded as being a better transmission than the TKO.

That's what I was hoping to hear I pulled the engine and Trans together. And figured while it's out now would be the time to get a new Trans. To install are removeable cross member i would have to tow it to a shop for the welding
I researched the SS 700 and that may be too beefy for my driving needs

Hi Folks,
The RS400/500/600 models are in production now, and will be shipping in the coming weeks. The RS are NO CUTTING in ALL CORVETTE.
The predecessor to the RS is T45RS, which we have been selling since 2007. In a C3 4-speed equipped car, the T45RS required extending the shifter hole to the right about an inch. This is NOT required for the RS. The RS uses our new PerfectFit design parts for a not cutting, perfect fit, correct driveline angle install.
There are people running the T45RS600 on Pro-Touring.com. Go on there and look at the threads on it, and you can ask them questions.
Alan Covin, the editor of the former Corvette Fever magazine, did a full feature on the T45RS500 in 2009. And you can see his driving video at www.keislertv.com. He was very impressed with the transmission, and liked the shift quality much better than the TKO.
