[MarksM]

Finally using some of those parts I see.... looking good.

if you have a free min, could you maybee put a parts list with part numbers up on this post. maybee it can be turned into an Install DIY.

thanks

I have been throwing around this idea myself to swap my m5r2 for a t-56. What did you do about a drive shaft?

......But search can work.
I listed a lot of part #'s in this thread for my swap.

Ok, in all honesty you may never actually complete a total install in one weekend without a lot of groundwork being done in advance, but the actual installation is quite doable.

Here we go.

First off, the ground work:

You'll need - A working T56. In this case we took an early Camaro Borg Warner T56 and updated the front cover and input shaft to a late model so that it would accept a diaphram style slave cylinder which we purchased in advance from McLeod along with a SBF bellhousing/SFI blowshield and separator plate. We used a custom McLeod lightweight billet steel flywheel and in this case a twin disc McLeod clutch originally designed for a 4.6L Cobra. Then we had to make sure we had all the right attaching bolts (none of the stock stuff or anything that came in any of the kits worked) and clutch line adapters for the master cylinder and -3 AN lines. Then you'll need a special lengthened driveshaft which we had custom made by Dynatech. I also made, in advance, a custom bolt in crossmember from a modified stock SC unit as can be seen in the pictures. A Z-handle on the stock Camaro shifter took care of boot alignment as the pictures show, requiring only minor trimming of the transmission tunnel.

More to come! As the weekend progresses......

All of that was handled in advance, and

custom shaft and modified x-mem.

This is pretty cool....looking forward to how this turns out.

Still having problems with the McLeod twin disc clutch. Once I get that figured out it will be on the road!

Wont disengage still Dave?

[talonhead]

Hey Dave,
Have you tried shimming the pressure plate on the flywheel. McLeod told me a while back that I needed a shim ring to get the correct clearence for disengagement, but I am using a stock flywheel and pressure plate with their disc. Reason was that their disc is several thou thicher than stock.
Don't know if this will help.
Good luck,
MikeH

Any update to this Dave?

Haven't had time to pull the trans back out again, other pressing projects. Will be taking it apart again soon to closely examine what is going on in there.

Not sure if this is helpful or not, but figured I would post it anyway:

Ok, so finally got to drive the car yesterday. Went the roundy rounds on the twin disc clutch and still have some issues to resolve, but so far making good progress.

The stock SC master cylinder has too much mechanical advantage over the Mcleod slave cylinder. From my discussions with McLeod it seems that the desired master piston diameter is about .700" whereas the SC master is about .900. This means that we achieve full extension of the slave very early in the stroke and as a result the pedal is overly firm and doesn't travel all the way to the floor. I think the solution here is to get an adjustable quadrant from McLeod to increase pedal travel.

If you were just into drag racing then this would be ok. You'd need to fabricate a pedal stop so you don't pop the slave seals, but it would be great for shifting quick, having only about 2.5" of pedal travel.

The tranny shifts nice and the clutch is awesome. Spendy, but awesome. On an extreme build like this one I think this is the only way to go.
