Correct flywheel and clutch - 6.4 w TKO 600
« on: June 18, 2017 - 12:00:59 pm »
So I finally decided to bite the bullet and swap my 440 for a SRT8 6.4 392. I am now shopping for all the parts I will need to make this swap. I have the engine and got a great deal for a Quiktime 8076 from one of our members. I am now looking for flywheel and making sure if my current clutch will work with this set up.

So the question is what is whether a 130T flywheel is correct for my application? Also, will my 18 spline 130T clutch work with this swap or is it necessary to have 26 spline?

Thanks for all your help.

Daryl

Daryl,
I looked on Ebay and got lucky for a brand new clutch, pressure plate and flywheel from someone using a 6.4 crate motor for about $350.  Yes, 130t is the correct one, not sure on the clutch disc, I would 'assume' you need one with correct size (10.5 vs 11).  I have a TKO600, just pulled my 470, and had to buy a new Quicktime bell.  Hope this helps

Thanks for the reply. Boy did you get a smooking deal. I just bought a bellhousing and am looking at an 8 bolt Hays 130T flywheel that I think is right for my application. My current clutch is an 11" 18 spline. I believe it will work but seems that most are using a 26 spline. Not sure if that will be a problem or not. This is why I am looking for input.

I do think you are fine with the 18 spline.  One issue I noticed is the bell housing for mine is small and will only accept the smaller factory clutch and flywheel, not sure if yours is the same.  Just a note, when I used my 470 and the TKO, I used a Chevy clutch and pressure plate, so I know they inter change to a degree.

You can't use an 18 spline clutch disc on a 26 spline input shaft of the TKO trans.

That is good info and raising an interesting point. See, when I bought my Cuda the owner stated that the car had a McLeod twin disc clutch but when looking through the receipts that he gave me I only found a receipt for a RAM 18 spline clutch. I am starting to think he bought the RAM clutch thinking that it would work with the TKO 600 and then changed to a McLeod once he realized it did not. Perhaps he just did not save the receipt or include it with the others.

But this does open up another question. If I do have a McLeod 26 spline twin clutch, would I already have a 130T flywheel or is there a chance that it could be a 143T? I have to change the bellhousing because I am going from a big block to a small bolock and the Quiktime bellhousing only allows a 130T.

Thanks again guys.
Daryl

Daryl, sorry now I am a bit confused - Usually hemi/6 pack 833's have 18 spline transmissions, others are 23 spline, TKO's or many modern transmissions have the 26 spline input shafts.  Correct, you cant mix them due to the spline count.  So which transmission do you have? 

If you have a TKO, you have a 26 spline - 18 will not work.  Again, issue is the size (143 is larger) to fit inside the scatter shield.  My small block (hemi 5.7) only allows enough room for a 130 t flywheel. 

Apologies, I may have missed the initial question, but bottom you can generally mix and match some items, but concerns will always be size, balance and spline count.  Being I have a 130 flywheel 10.5 flywheel with a GM 26 disc and pressure plate, no issues.  (Summit has them on close out for very cheap many times)

Hope this clears it out

Sorry if I confused you. I have a TKO 600 tied to a 440 currently.  The previous owner told me he had a McLeod twin disc clutch in the car. But when I was recently going through his receipts I found a receipt for a 18 spline Ram  clutch and not the McLeod. I now figure that he bought that clutch mistakenly and then had to purchase the McLeod when the other clutch didn't work. Guess he never saved the receipt.

So I must have a 26 spline but won't know if I have a 143T or a 130T flywheel until I drop the motor. Unless a Bb 440 bellhousing use a 143T and not a 130T. I figure I can contact Tremec and find out.

Thanks guys. You have been very helpful.

Don't know if mine will work. I accidentally bought an 8 bolt Hemi fly wheel instead of an 8 bolt flex plate. Its brand new and just sitting in my dining room floor. If the team thinks it will work I can post some pictures. Most likely going to a new 392 it won't bolt up. but I'll throw it out there incase anyone else has need of one.

Daryl - gotcha, Sounds like you have the same general setup I had with my 470.  My housing I will be installing behind my 5.7 is Quicktime 6070, what is your bell housing number you will be using with the 6.4?  Just a note, I would probably not be counting on using the flywheel from your 440, the 6.4 has different balancing.  I would look for one specifically for the 6.4, the clutch and pressure plate you probably could re-use.

Talked to the previous owner today and he said I definitely have the McLeod twin disc which I assume is a 26 spline. I am going to use the Quiktime 8076 which is for the fen 3 Hemi. I emailed Tremec about the flywheel so hopefully I will know soom if I have to buy another but my clutch should definitely work. Found a good deal on a Hays P5153593 which looks correct but waiting to pull the trigger until I am certain.

Now all I need is a plug and play, radiator w fans and some headers. Plus a few other things. In no rush because I am not planning on doing the swap intil the fall.

Thanks again for everyone's help.



73cudabr - will not work.

went through this years ago with my 6.1L ---  used a 130 tooth flywheel and a McLeod 26 spline clutch...    I used a belhousing from Keisler (appeared to be a modified truck bellhousing) --- this was also 9 years ago when these parts were not common and no one had really done a gen 3 hemi swap besides Autodynamics over on DC.com

Thanks for the info. That is the same thing I have found from doing my research.
