t56 flywheel help

I Bought the fidanza aluminum flywheel. with stock clutch (we'll see how long that lasts)

 

I have an older (pre-86) two piece rear main seal i plan on mating to a t-56 and there is a special "conversion" flywheel you have to buy for that setup.

 

Ram and centerforce also make flywheels that work but they are around 25-30 lbs and made from steel for $400.

 

The fidanza is made from billet aluminum with a replaceble steel face for $425.00 and weighs in the 15lbs range. well worth the 25 bucks if you ask me.

 

Course i lucked out and bought mine off a craigslist as for $125.00. guy was selling a lt1 clutch with pressure plate...well that was all bolted to "something" and the something happened to be a fidanza flywheel that just so happened to be the exact flywheel i needed! :)

 

needless to say I was very happy to pay the money i did for it!

 

PM me if you have any questions...I can look up part numbers for u but ure looking at $400+ if your mating it to a pre-86 block.

Do a search for this, it has been covered several times before, I was going to do a T56 from and LT1 to a 400SBC two piece before so I know there is a thread on this and several others already, I think I remember a McCleod balanced flywheel with the LT1 pressure plate and clutch.

I used an old Weber Aluminum flywheel(standard old school aftermarket part), along with a LS1 bell housing. I had to fabricate a new pilot bushing that extended farther to the rear. a Hydraulic T.O. brg was used as well as a 3/4"(?) spacer between the bell housing and the trany. Standard SBC clutch disc and PP were used.

FWIW

The McCleod you have is for a 86 and up one piece main, there are ones for Gen 1 two piece available for LT1 type clutches as well both zero balance and balance for gen 1 blocks, I know because I have talked to several people at shows that are running gen 1 383 strokers with new cranks with no balance and 400 SBC cranks that need the external balance on both ends, Balancer and flywheel. Both 1 piece and 2 piece flywheels for an LT1 clutch are available from McCleod and Centerforce and several others in zero balance or Balanced form

Besides my old thread that Redneck found there have been some even older and newer threads on this, I think the CamaroSS forum had some info as well.

 

Here are a few places I had in my Archives while I was researching this, I don't remember what each had to offer right now but If I kept them then they were useful:

Good Luck

FYI I am still looking for the right 400 SBC for my Z car as long as I can sell both of my LT1 motors, computer, software, harness, go fast goodies etc.

It is not high on my list right now because I am enjoying the stock LT1 and the good highway mileage.

As far as i know the t56 uses an electric signal and the stock tac doesnt. I could be wrong i havnt looked into it yet, just waiting to get everything balanced now.

 

Dunlop:

 

Likely you are very correct. I also have a T56 that came from a 93-97 camaro/firebird and it has an electronic pulse output for the speedometer. It is only recently that new T56 are manufactured with either electronic or mechanical speedo cable output. The latter requires proper speedo gears to match up with the mechanical speedo in the vehicle. The modern electronic speedos are much easier to interface to modern custom speedos.

I opted for the Auto Meter electric speedo instead of one of the Cable-X boxes, although with the electric speedo it is easier to calibrate for tire/wheels size. Drawback...coming up with a solution for the turn signals and hi-beam indicator.

It's been done both ways here on this forum, oh and a third I think is having JTR modify your T56 tail piece for a mechanical set-up.

 

Glad I could help with the flywheel issue.

I am running the stock GM clutch, pressure plate and throw out bearing, I had the pressure plate cleaned and surfaced and bought a new GM clutch disc for the 95 Camaro/Firebird, there are a lot of articles on the various "Stages" of clutches and pressure plates that cost tons of money but ti turns out the T56/LT1ressure plate is made by only 2 companies and is the exact same unit you can but from AutoZone or Advanced Auto for much less money, The fancy clutch companies just paint or powder coat the exact same pressure plate with a nice shiny bright color and then charge you big bucks for the same pressure plate. Most smart guys on those Camaro forums buy the AutoZone pressure plate kit and keep or toss the clutch disc that comes in the kit and just buy an upgraded disc.

I forget which F body forum it was but most have very extensive discussions on this stage kit or that stage kit and if you dig through all the bullshit you will find the guys that have discovered this little secret on the pressure plates.

I might of saved a link to this topic, as I usually do save most links that I find worthwhile.

I'll search through my Library of links.

Well i am back to square one.

 

My flywheel doesnt work because the clutch i have has a push type throw-out bearing vs a pull type.

 

So now i need to find a new stupid flywheel. Also now i am confused on what clutch to buy now, just the one that was for the 93 firebird that the t56 had????

 

 

Please help me
