I did some measurements to see if I need to shim the slave. New GM slave, TOB, measured with spring removed. Flywheel and pressure plate torqued to spec.
I came up with 11/32 difference. Seems like a lot to me. I was gonna order the shim pack from Tick. Am I supposed to use 2 shims to bring it to the correct measurement? I could use a .180 and .113 shim to bring it close but it doesnt seem like I should need 2 shims.

I may be thinking this wrong. From the Tick website it says the b measurement should be 3/16 to 1/8 less than a. If not shim the slave.
Am I shimming the slave to get the desired .125-.200 clearance?
For example, my measurement was .343.
Tick recommends .125-.200, so if I used a .180 shim, it would bring my 2 measurements to .163. Is this correct?

Im waiting on a few parts. Shim, submersible fuel line, O2 sensors, plug wires, header gaskets. Spoke with Tick and ECS and got everything cleared up, it will be ok to shim the slave. Thanks to both. Everything is looking good and I have been taking my time to do it right, I hope that pays off.
Modded my fuel pump bucket to fit the bigger pump and it turned out real nice, Im happy with that.
The parts I need to finish everything up should be here Friday, so Ill be putting as much as I can together over the weekend. Im glad Im doing this. Ive learned a lot. In all honesty, I swear the hardest part so far was getting the damn fuel pump out of the tank.

Well, just finished up tonight and took it for a spin. I didnt go but maybe a block because it smelled like the clutch was burning. Im guessing the clutch isnt engaging all the way. Looks like Ill be spending another few weekends pulling it back out to most likely pull out the shim that Tick told me to install, and ECS was more hesitant about it. 
Im not happy.
My fuel pressure was great though!!

Sorry to hear that, although like I said, you would have been the first Mantic I ever heard of having to shim. That's a bummer.

Can someone explain something to me please. If I used a .113 inch shim, is that tiny amount enough to make a clutch sound and smell like its not engaging all the way? I got the car all tore down last night. I was looking up at the slave cylinder and it looks pretty compressed up against the pressure plate. I would think there would be more distance.
I also saw that the shaft that comes out of the torque tube still has some teeth showing. I didnt notice that while installing it into the pilot bearing. I dont see how it could not be seated all the way into the bearing, it all went together nice and smooth. Didnt take much effort to seat the bellhousing and bolt it up. It wont go any further in there.

Did you take the measurements for the shim? Should be from the pressure plate fingers to the bell housing surface minus the torque tube surface to the top of the throw out bearing with the bearing fully seated(take the spring off). Is on tick performance's website. If its greater than .200 use a shim to bring it it.

I took the shim out and put it back together again and I just happened to notice that 4 of the fingers on the pressure plate arent seated on the throw out bearing. Looks to be about 1/32-1/16 inch space on just those ones. I have a feeling thats why my clutch isnt engaging all the way. Is that a pretty good guess? I should probably start taking it apart.

not undestanding
I've seen several guy's with theses clutch's in person including myself. Great clutch its a direct replacement. No problems what so ever at 450 wrhp and almost 5k miles later. It gets a little tempermantel hear and there in traffic / grabby plus real big cam. But hell it wants to go. Great clutch bolted it in no measuring no thought. It does stink a bit from time to time when slipping it to back into a hard spot . It just keeps on going and doing a great job. Dont over think a process. Just my 2 cents. I will happily put there twin if I go supercharged

It was a mistake on my part. I followed the directions on tightening the bolts down half a turn at a time. For some reason or another it didnt tighten evenly and the pressure plate fingers were uneven. Loosened them back up and after a few tries got them even. The clutch is great, grabs each gear quick. Way better than a stock clutch with a supercharger.
