Right now I have a McLeod single disk on my car with the mods listed. The first thing I did after installing the clutch was go down the street and romp on it through about 4 gears. I have about 3000 miles on it now and the other day I still got a 4th gear scratch.
Work on just LS1 based cars for the last 5 years like myself and you'll see

sounds to me like your synchro in the trans is going out... mine started doing the same thing... transmission rebuild came 2 months later hehe if i short shifted it wouldnt grind, if i shifted at a high RPM it would grind... every time...

i have the spec 3+ in my car with billet flywheel, stock slave, new master, never had any problems with grinding once i got the new trans.

I hope it was just a flywheel issue, I pulled it back out and it appears that the Flywheel had been cut before So I ordered a new flywheel and Slave(Its leaking) The car wasnt grinding before the clutch when out....So i am hoping with the thin flywheel it wasnt releasing the clutch disc all the way

if the flywheel was thinner then you would have problems engaging the clutch.. not disengaging.... you would have enough pedal to disengage it but not enough to engage...

If the Flywheel is Thinner it is further away from the slave, So when you have the clutch Petal pressed in "Like Shifting" It in NOT releasing the clutch disc....Because the slave is not pushing the pressure plate in far enough.

wrong.. the distance between the slave cylinder and the pressure plate fingers does not change... when your flywheel or pressure plate or disc wear out the pedal keeps getting higher and higher, and disengages right at the top of the pedal. when you push in the pedal it pulls the pressure plate away from clutch disk. the more worn out stuff is the higher the pedal gets with the disengage/engage point.

OK, The plate and disk dont change postions because they are Tight up against the Flywheel, BUT if the Flywheel is thinner that changes the postion correct? Moves it all in towards the front of the car? There for the Slave is not pressing the fingers of the Pressure Plate in far enough to realse the clutch. As far as the wear of the disc the figers move out to correct that, But once again if it is all too far away to start with .......

hrmm... there is no way your flywheel has been machined that much but your correct... that amount would be minimal compared to if it was worn out though.. did you install the shim that came with the clutch??? sounds to me like you didnt which is why it does not have enough "throw" to disengage the clutch... you 100% positive you installed the shim behind the slave cylinder?

and btw.. i have heard of some cars with rebuilt transmissions needing 2 of the spacer plates because when they rebuild the trans they usually machine a little off the mating surface the slave cylinder goes on... sounds to me like you need some extra shimming.. either way... shim = cheaper than a new flywheel.... if its not disengaging then its either air in the system, or a shim problem... those are pretty much the only 2 culprits when it comes to "not disengaging"

Yeah Bro I am %110 it had a shim. I really thing the Flywheel Has had the **** cut out of it(Before I got the car) The dam pressure plate bolts stuck so far out the back I thought they might hit ****. My new Flywheel, Slave and Master will be here In the morning so we will see. I really thought of two shimming it but I decided just to get the new flywheel. PS when the Flywheel wears It only wears where the Disk rides not where the plate bolts up. When they surface they cut the whole face there for the Pressure Plate can not correct that. Anyway how do you like the Spec 3+?? How much Power are you making ??
