ZF6/Mcleod install progress
I installed the Mcleod aluminum flywheel today without any additional balancing aside from the counterweight installed by Mcleod. I was very concerned about vibration after reading a lot of threads here, but I could not detect anything abnormal up to 6500 rpm. I was told by Exotic Muscle that there is no special engine balancing that was done at the factory for the LT1. The LT4 however did receive individual balancing.

How did you like the hydralic throwout bearing? How does it change engagement/disengagment of the clutch? Does it require a different master cylinder other than the 13/16" unit Mcleod already supplies with the Street Twin?
How long did you break in the clutch? Is it excessively "grabby" or just agressive? Did you go with the aluminum flywheel?
Sorry for so many questions... I'm just really anxious to get this on the road and row the gears!!

after i got stranded because the hyd line to the bearing got caught in the pressure plate, i created a hold down clamp to the back of the bellhousing to keep it away from the clutch. biggest pain in the a ss was setting the clutch finger distance to the face of the t/o bearing to get a full disengagement without riding on the fingers. when i put mine in ( 92 0r 93 ) mcleod did'nt offer a master cylinder so i used the stock one. just had to get a braided hose long enough from the master, through the bellhousing ( drilled 2 holes in the side ), and to the bearing. then from the bearing back out the bell housing and a pigtail long enough to bleed the system.
my setup had the aluminum flywheel, a disk, spacer, disk and pressure plate, and the breakin consisted of going to the track and launching it for an evening, and it was'nt grabby.
i have since pulled it out when i quit racing that particular car and went back to the stock setup, but i still have the clutch and hyd bearing. will start to build an 86 soon as a dedicated race car and have'nt decided to run this setup or go to an auto.

Cool, thanks for the information. I was a little worried about a twin disc setup being a bit of a handful on the street, but I have been told by a few now that it will be ok.
