Project Evade Upgrades from TKO-600 to Tremec T-56 Magnum
“To improve is to change; to be perfect is to change often” A few months ago I finally pulled the trigger and decided to upgrade and install the T-56 Magnum here listed is the complete install "Installation by Tom Argue Design" Parts List:
T-56 Magnum Transmission # TUET11009 GM

QuickTime Bellhousing Chevy LS to T56 # RM-8020
Centerforce New DYAD Clutch and Presser plate # 04614842
Getting the T-56 ready for install i did a lot of research for installing T-56 without Tunnel modifications ... The T56 is a larger transmission than your stock transmission. and the TKO If you are using the proper LS motor mount kit, the LS T56 will fit in the tunnel of the 1967-1974 Camaros without having to cut or enlarge the tunnel. Note: If you are using incorrect LS motor mounts, if you have shorter, non-stock sub-frame bushings, or if your stock bushing are worn and compacted, the T56 may not fit within your tunnel without modifications
With having the Complete Speedtech sub-frame- LS Motor mounts and the Solid body mounts the T-56 fit like a glove !
We changed the lakewood bellhousing to this SFI-approved Quicktime scattershield. The main benefit here is that its compact design takes up less space in our already crowded trans tunnel.
The new DYAD DS twin-disc Part # 04614842
Every DYAD DS clutch that ships from Centerforce comes with what they call a “birth certificate” specific to that unit. It gives all sorts of helpful data like compression depth, travel to release, average clamp load, and most importantly, the average torque holding capacity. In our case it’s 1,387 pounds.
Centerforce’s solution was to lighten up a steel flywheel. By removing weight from the outer edge, the flywheel gains much of the benefit found in an aluminum flywheel.....“The entire assembly weighs 45.8 pounds!
The DYAD DS is a ‘true sprung’ hub design with the main drive disc built from chromoly steel. The drive disc also has over an inch of spline engagement for stability and strength.
The floater then went on and was held in place by the three lugs on the flywheel. Centerforce marked both of these parts with machinist’s ink to let us know how to orientate them.
The floating disc is held by six drive pins rather than on the input shaft of the transmission. This meant aligning the clutch parts was a snap.
With all the discs in place, Tom could go ahead and install the pressure plate and secure it with the included high-strength fasteners.
Now with the T-56 installed we adjusted the speed tech cross member back to fit and in order to get the correct pinion angle we to custom cut the cross member a half inch drop
Now with the Cross-member all welded up fits perfect !
