440 w/ Viper 6 speed

[stey235]

I just purchased a Viper 6 speed to put behind my 69'-440 going in my 41Dodge Coupe. It's getting an Aspen front clip and A body 8 3/4 rear end. Any ideas or problems with this set-up? All suggestions / help is appreciated.

wow..cool sounds like fun, id like to know what mods you had to do to get the two to mate up.. keep us posted, i like to have one in my cuda

I 've been thinking of a 6 speed behind a big block dodge.I'm also really interested in how these 2 bolt up. Especially the clutch and pedals. I belive they have a hydraulic clutch. My chevy buddie put one in his camaro.What alot of work it was. Still I'm still considering one for a vintage mopar. Keep us posted,thanks the toolman

got a question for you.. I was looking into getting the viper 6-speed, but came across a t-56 from an LS-1 motored car first. is the viper bellhousing a direct bolt up for the small block or big block? I even called mopar tech, they couldn't anwser, and called a viper performance shop.. nobody knew.

[jleilich]

i know its not a 6 speed but that company i think is called Kiesler makes a "bolt up" 5 speed, comes witha drive shaft and you can use a pistol grip too. they advertise in all the mopar mags

[stey235]

jleilich the Keisler unit is nice but also sort of out of my budget. Besides the Viper has 5th and 6th overdrives. 6th has a ratio of 1.0 to .5, which should make for a good cruizer.

two thumbs up to the 6 speed. and the viper version is even stronger then the one that I have.

I've talked with Richmond tech guys about adapting their 6-spd to a big block mopar. Apparently it will take bellhousing, tranny tunnel, driveshaft, clutch, .. etc modifications, but it isnt all that impossible.

[Mach Manny]

oh, and Richmond is for Chevy applications, so you'd need to use chevy speedometer parts and ujoint

[jleilich]

so what would it take to mate up a viper tranny to a big block, ???? if it is cheaper than the keisler i am interested..

[ChristianCuda]

From my understanding The viper uses the same bolt pattern to the block as the Small Blocks. So essentually you could very easily bolt it up to a small block. Now A big block would require a different bell housing or an adapter. Currently that I know of there is not a bell housing for the Viper 6-speed to the Big blocks. This would mean a current Big Block bell Housing will have to be modified to bolt to the Viper Six Speed if it s possible.

Please keep us posted on what you find out.

BTW how much did you pay for the 6-speed? If you dont mind me asking?

[loki993]

if what youre saying is true, that a viper six speed is a direct bolt on to a small block im all over that. im very interested in this whole thing so please keep us all informed.

[jleilich]

for the big block ,, you couldnt use a lakewood bell housing or something,, and what do you mean by modify it, do you mean drill new holes or actually weld or take out some stuff..?????

[curious]

well that would be a cool swap but i have a truck. that means NOT cool shifting. the first v-10 was supposed to literally be a 360 that was hacked and slashed so my guess is it would work. and i saw some where where they adapt a TF-904 (only has small block pattern, duh!) to big blocks. maybe the same adapter would work on the 6 spd?

[dewme5]

you can just get a 1/2 adapter plate that is goign to mate a small block tranny to a big block, and then a matching 1/2 spacer that is going to go between the crank and flywheel. this second piece is also going to have to have a provision for a pilot bearing.

the advantage to using a 6-speed from a LS-1 motored car (98 or newer), is the length of the input shaft. you don't have to use the adapter to move the flywheel. just the 1/2 adapter for the tranny to the block. that should work the same for a big block or small block. just need a spacer that is going to mate a powerglide to a big block or small block, and most of the rest is going to be a piece of cake.

still wish i had the viper tranny though

[Mach Manny]

The lakewood housing between the Richmond 6 speed and a big block crankcase would need to be drilled and adapted. The tech guy didnt mention welding/cutting to adapt them.

[stey235]

I contacted Lakewood and was given the phone number of their R&D deparetment. They will have this exact bellhousing ready for the market by next summer. I was also given the opportunity to have one specialy made at a reasonable cost. Wade from Lakewood was really helpful.

The Viper trans definatly WONT bolt up to a small block. I had a chance to slide the two together on the ground and while the patern looks the same the Viper is at least 2" bigger diam. As far as the big block I have no idea.

[Knockexperte]

Does someone have the different Big Block bolt patterns?
The bellhousing bolt pattern for the Viper I do have, so comparison is possible.

Keisler doesn't make the transmission that they sell. They are Tremec transmissions.

The Viper 6 speed is also a Tremec and is also used in the corvette. You can get the correct bellhousing from Keisler. Lakewood may also have the correct bellhousing.

[dewme5]

while the viper is a t-56, there are differences between that and what is used in the vette's. specifically the input shaft, and some other that I'm not sure of.
