2017 C3 of Year Finalist
My car is 1970 with a 350 and originally a Turbo400. There were no mods needed for the chassis and it was a “PerfectFit”, or as much it can be for a 44 year old car anyway. Seems like even though these were all built the same and on the same factory line, they are all just a little bit different from each other. I did have to buy a smaller starter as there were some clearance problems with the one I had. The shifter hole on the tunnel was for some reason bigger than the plate that came with the kit. We just fabricated a new one which was not a big deal. The real pain was pulling the dashboard out on the driver’s side to install the pedals. And it’s different car in the sense that manual transmissions in Corvettes are just plain fun, and the fact that I can cruise at highway and interstate speeds in complete comfort. I’m turning about 2000 at 75MPH in 5th gear. Night and day difference.

If you go with a Richmond, get a Long shifter. They are miles ahead of the Hurst. Also, use Redline's manual transmission fluid (not rear end gear diff oil). It smooths out the shifts alot due to higher friction for the synchro's. The 5 speed fits perfectly in a C3 and you only have to modify the transmission mount some, which they provide instructions for in the installation manual. 
Street 5 speed
5 Speed road race
Street 5 speed with O.D
When I contacted them most of these transmissions are not being manufactured
The Super T10 4 speed can be purchased and will be releasing the Super Street 5 speed very shortly but the 6 speed is not being offered at this time.

I originally purchased the street 5 speed 10+ yrs ago, and have subsequently modified it with the 5 speed road race parts. However, Richmond has been purchased by another company and I know the transmissions/parts can be hard to find right now.

I just checked out their website. I wanted to see some ballpark prices so I could see if it was something I could afford. The only option I saw was 'contact us for a quote'....I think that will scare many guys like myself off who think "if you have to ask, you cant afford it'.
-Base TKO 5-600 kit $3499.00 (through 12/31/2014)
-Add $1240 for an auto to manual conversion (C3)
-Add for shipping based on location
TO ALL: Would the ability to purchase these kits directly though the website without having to call be appealing?

We don't have any official discounts running other than a year end promotion but that doesn't mean we can't be talked into something additional for CF members.
Our half-off-triple-the-price discount is my favorite.
Give us a call.

I have been looking for over a year to upgrade my Muncie 4 speed transmission with a 5 speed in my 1968 427, 435, 4"11 Corvette. After much reviewing, calculating and sole searching, I placed my order with Silver Sport today! Can't wait to get it installed and get the benefits from the overdrive!!!

With some dealers of parts advertising prices can get them in trouble with the mfr. Good to see somoene has picked up the ball on these trannies and making them available. If you want one just call.
Have a t56 which is a good trans but if I had to do it over id use a stout 5 spd without such a low first (like the typical 3.08) gear. 6th is super tall on a T56, a different 5-6 gear cluster to change it out is NOT cheap. 2.88 or 2.66 is better for first imo

I believe the tko 600 is stronger, so it depends on your torque. I installed a tko 600 in my '69, they are a pretty easy install and they are pretty much a bolt in.

Any recs to replace my Muncie M20 4-speed? The car is a 454cu.in. engine that when done should have about 400hp with 3.36 gear ring and pinion. Just looking for fun cruiser with tolerable RPMs on the highway. Also would like the 'perfect fit' idea with the shifter in the stock location. Should I go say 3.73 gears with 5-speed overdrive? Thanks!
