6-Speed Conversions?

[C10 - C90 Bill]

I was just talking to someone about 6-Speed Conversions and wondering if anyone out there knows of any kits available for our '67 to '72 trucks.

I have a '72 C-10, 307, 3-Speed.

Not sure I want to convert to one, but I am interested enough in one to read up on them and to consider what the cost would be.

Any info would be appreciated.

crazylonghorn has a Richmond 6 speed in his truck, hopefully he'll chime in here.
I am planning on a Tremec 5 speed swap myself, classicchevy5speed has really complete kits available.

[C10 - C90 Bill]

Thanks,

I checked out ClassicChevy5Speed and that TKO-500 looks pretty good.

But are there any complete kits out there to install one if I already have my own trans?

There a couple shots of the Richmond http://community.webshots.com/user/hotrodhorn pretty straight foward bolt in, but the shifter is a long way back for a bench seat....L

i figured it out one time,

if my memory serves me,

its about 4 grand to swap out to a richmond 6 speed, all from summit racing.

Yea, it did take a BIG bite out of the wallet it went in where a 400 turbo came out , with no driveline mods(26 spline clutch, & move the crossmember). I run a stretched high hump pan, with a custom shifterbox added to the rear. the 400 slipyolk works also....L

Contact Keisler Engineering they should be able to hook you right up, if you want any further information I swapped a t-56 into my '67.

thats the plan for mine, carb'd LSX with a T56

I put an ROD 6 speed in a 59 'Vette. Custom trans crossmember and driveshaft shortened 3" or so from Muncie 4 speed. Then 3 of us spent a day working on moving the Long shifter forward, and we got 7/8" out of it. I had to trim the body a tad for the shifter, but the hole in the console was just big enough. All the stock clutch and bellhousing stuff worked fine. No kit was available,and I think with the shifter he was $3600 into parts. Besides the shifter, it was a pretty easy fab job.

Pics are always appreciated

[69halfton]

im looking into it a bit...

does a richmond 6 speed fit into the automatics transmission tunnel?

or is there ALOT of cutting needed?

My truck is body dropped, & the 400 turbo didnt fit the stock (low hump ) tunnel. I cant answer that ? for sure, but I think if you are in correct factory small block spot, it would be pretty close. I run I 6 spot on the stands, & it took a stretched High hump to fit the trans & shifter. The shifter mounts high & right at the rear of the trans.....that would be the trouble spot. L

What was the T56 originally used in?

You'll have to excuse my knowlegde as it pretty much stops at 1972.

Do you have the part numbers and info from your install? I have a 68 C-10 that I would like to do a six speed mod, vice the 4L60E that came with the LS-1 motor that I have to put in it. The seats and the driveline are no problem here.

Some that come to mind are: Corvette, Camaro, Firebird, Viper, GTO, Mustang, Cobra, etc. There may be more. Both Borg-Warner and Tremec make a T56, and you will see there is the TKO also, which may or may not be related.

Just curious was it a pain setting up clutch pieces , is there a kit or did you find a donor truck ?
I have a ROD I am thinking about swapping out the T350 for.
thanks....

Thats a LS 364, which is the LS2 that GM offers with the manifold in a crate. Dealer gave me a price where I couldn't justify stroking my 350. Of course I spent it all again on the tranny but it makes me happy

Now if only ECE would get those sandersons made

I run a 66 truck bell(4 11/16" center hole), the flywheel is a Hayes billet(you can run stock). The centerforce clutch set is a bolt in 11" set for the truck, but runs a 26 spline hub instead of the 10 spline truck pc. All of the stock clutch linkage pcs will work, but the rod ends "free" things up a bit. The trans is close enough in lenght to a 400 turbo, & has the same spline to use the 400 slip yolk. I would say if you run factory sb spot, use a 6 cyl /4spd 2wd high hump pan(they are a little longer), & modify as needed. IMO, the tin work is easy. My trans crossmember is custom built, but you can modify a factory auto trans member to fit the bill. Your 350 turbo is also close in lenght, but needs a slipyolk change. If your 2 pc shaft has a slip in the middle, you can "fudge " on the lenght a bit also.....just be sure to have 3/4-1" of slip, so you dont slam the trans. If you get into the build, & have any ?, feel free to ask......jog this old mans memory, on anything left out. best of luck,L

The LS 364/440 w/MSD ignition was what I had originally planned on for mine, but then decided I wanted to go with the LSX block. Its iron so it can be bored conventionally, has 6bolt mains, accepts all LS1/LS2/LS6/LS7/L92 parts(including 6 bolt heads), bore x stroke goes up to something like 511ci, and it can handle up to 2500hp...which is a lot more then mine will be putting out.


.....unless there are more deals on the LS 364/440 that can't be ignored!???

oh...and yes, I'll have a build thread! I haven't bothered with it for phase I...which was to strip down my '72 and my '68, and install my '68's body on the '72. Now I can strip down the rest of the '68 chassis, get it powder coated, and begin the build. In the end it will be all new as this truck will be mine for many, many, MANY years to come.
