The problem started about a year ago, after I did the h/c on the camaro. I've been trying since then to remedy the problem. Things I've changed:
Transmission fully rebuilt.
Tried a different tranny with the same results
Replaced the Mcleod adjustable mc with a Tick setup
Replaced the Mcleod clutch with a new Mcleod clutch
Replaced the Pilot...
System has been bled several times.
Any info or suggestions would be greatly appreciated. I have no idea what else to do.

Is it hard to get in to first or any other gears (reverse and first usually)
What flywheel are you using? You might need a shim to allow full and good engagement of clutch (my situation right now haha)

If you have done all of that to the trans and clutch setup, including a rebuild and a diff tranny as well as all new hydraulics, I would say stop looking at the clutch/trans set up. Focus on the shifter or the pedal maybe?

Check for leaks by the bell housing, if you see any fluid, could be slave leaking, but that wouldn't make any sense for it to change to different difficulties randomly. It seems odd... Is 4th the only one that high rpms dont like? and do you have to really really put it to the floor to engage the clutch and get in first?
also, what flywheel you got??? jw.
and when u did the rebuild did it include the shift forks? I had a similar issue in my other t56 and everyone thought synchros but it was shift fork that was bent. I believe the shift forks are aluminum and can get bent easily and seeing as there are 3 shift forks for your gears, it could only affect a gear or 2 if bent. (been a while so if someone sees something im saying that's wrong, correct me hahaha)

You have a clutch hydraulic issue if its hard to get into reverse or 1st. This will show up at high rpm shifts as well. I would suggest continue inspecting and trying to resolve the issues with the hydraulics before trying to shift at high rpms to keep from damaging the trans.

The tranny hasn't been shimmed, but hopefully we can get it figured out with the help of the sticky in this section

I don't have any experience with the Tick version master cylinder but have done several of the older McLeod master cylinders and those were super picky about adjustment. You had to get them just right. Too much or too loose would result in issues with either hard going into gear or slipping on the top end.

^ yeah, I am thinking shim. It's the only thing left to try, and if you aren't having leaks, slave should be fine.

Thanks for the responses and suggestions. I had the Mcleod for a while but the pedal pressure was too hard and we had multiple issues trying to get the pedal to stay consistent. I'm not trying to knock Mcleod because I've run their clutch for 4 years of racing without fail.
The tick mc made a night and day difference in the way the pedal felt but ultimately didn't solve my problem.
The amazing thing is I thought the car would have to be towed to the shop. The last time I attempted to drive it, it was difficult getting it into any gear, with reverse being impossible without first turning the car off.
A couple days ago, I hopped in, fired it up, and the tranny engaged much easier. I was able to drive it 30 miles to the shop with the tranny shifting smoother the more I drove it. Once there, I found reverse was still difficult to engage but at least it would go in without having to turn the car off.

Well, the shim didn't work. I have no idea what else to try. I'm thinking the Mcleod clutch may be the problem. I'm thinking about trying the ls7...

I would love to see pictures of such fork. Who told you it was bent? The builder? Post pics....

Hmmm. with all said above it sounds like your boling the clucth fluid. On another note, I had the same issue way back in 04 high rpm shifting, I had my tranny rebuilt, bought a ram cluch. I had facotry hydrolics also. The only thing I did differant was I went solid mounts. I had the bmr stands and the solid tranny mount. I did nothing to the hydrolics and shifting at 7.k was no problem. I also ran the gm purple stuff for the clucth fluid.
