Found out that it would be a bunch of bull to mount a t56 to my 1973 block with two peice rear main seal, im starting to get frustrated! I really want at least a 5 speed tranny so i can have over drive cause im running a steep gear, anyone have any suggestions? I thought about the TKO Tremec but i think they mount to a one peice rear main seal flywheel as well. Ive always dealt with automatics in drag racing so im puzzled about the manuals....anyone who can help me out with what im gonna need?

Also i know this isnt the right board for it but i thought i would just let u guys know that ive designed my own under dash heater unit for our cars using some of the factory peices and a little fab work....the prototype isnt quite done yet and i still have a few bugs to get out but its gonna work! Im really happy it is because this now enables me to smooth my firewall where the stock unit was and gives me a place to neatly mount my Ignition Box and Coil. When its all finished ill post pics and give detailed instructions on how to do it......after all im not in this to make money just to help fellow third genners!

 

Why would it be a bunch of bull? I'm pretty sure Centerforce makes a flywheel that will mate a T56 with a 2-piece rear main seal block...

 

Forget Centerforce...go McLeod. I am sure that they have a flywheel to fit a 2 piece rear main seal to a T-56. It will cost you like $250-$300 though...

Good luck.

 

First try reading this... http://www.skulte.com/T56.html

This will tell you just about everything you need for the swap.

For the flywheel, Try Hays, Centerforce, McLeod

The TKO uses a standard type clutch so it'll bolt right in. Use the Lakewood bellhousing PN 150020 with a 168 tooth flywheel and an 11" 26 spline clutch.

Same goes for the aftermerket replacement T-56. Only the 4th gen stock T-56 uses the funky pull style clutch.

 

heh...yeah it will work. i dont have the part number on hand right now but when i ordered my flywheel, centerforce was the only company that was making a flywheel for a t-56 with a 2 piece RMS. call centerforce get the P/N and then call their local distributors, i got mine from a speed shop here for like $250 or so. its not really a PITA, you just have to do some hmwk and figure out what you need.

 

Well you could pay $300 for the Center force fly wheel or $$$thousands for the after market tranny, or you could just get the LT1 t56 and use an 83-86 F body t5 153 tooth flywheel and use some nuts to space out the slave cylinder about 1/2". This is the way I was reccomended to do it by someone who has already done it. Looks like I will have about an extra $250 to spend on some stuff to make me go faster. And that is not counting the money I am going to save by using a t5 clutch and pressure plate after I figure that part out!

Erik- :lala:

 

Interesting...post back when you get it done. Could be a real $ saver, but I'm not sure the little T5 clutch would stand up as well to drag launches and roadcourse downshifts.

 

The TKO application sounds alot better in my book, would i just use a clutch assembly and pedal assmebly out of another third gen? Im guessing it will bolt to the lake wood bellhousing but anybody that knows get back with me. I need to decide what im gonna do pretty soon cause a friend is interested in my TH350 if i dont use it

 

Why wouldn't a t-56 clutch work w/ any SB flywheel. Don't aLl the pressure plates bolt up to the flywheel the same? I am asking because I have a sb400 w/ a GM Performance Parts externally balanced flywheel(pn. 3986394) and am planning on using a t-56 from a 94-up.

 

Octane, if you use the Lakewood bell go ahead and use a 168 tooth (14") flywheel and clutch. I mean, if you can go bigger (stronger) for the same or less $ why not?

Camarosb, nope, the T-56 thats used in production cars has a different disc/flywheel/pressure plate than whats considered "normal". Your going to need an aftermarket flywheel. I'm not versed in the specific design differences or I'd give you more information.

 

Ya bigger is better in the clutch department, all set aside though......besides the throwout bearing, flywheel, disc, pressure plate, and clutch fork....what other things will i need to put a Manual in my originally 700R4 equiped camaro?

 

If nobody answers...given that this has been covered repeatedly...you'll want to read the Tech Article on this subject. Nice complete parts list included.

 

yup, sorry i didnt look before posting my last question , just found that article after posting last.....cant remember who did the article in the tech section butthey described things really well......now off to the boneyard to find a hydrolic clutch assembly!

 

hey octane I ran into the same problem. I didn't know what to do to get my T56 to mount to a 2-piece real main seal block. I luckily contacted Speedomotive at the same while ordering my 383 engine kit. they put me in contact with Mcleod to work something out and they do offer a T56 flywheel for the two-piece real main seal motors. It ran me about $275, I don't have the P/N but give Mcleod a call, I'm just letting you know that I have already been in your shoes and done it. While you're at it you should get the clutch disc from them and get a GM-performance parts LT4 pressure plate. They are best combo that I know of. Good luck with the project and let me know if you have any questions.
