Finally we have solved the problem :)
Further things done were change of the 8.75 gears to 3.23 instead of I think it was 2.76 - the shatter was a bit less, but still there.
Then we have took of the clutch again and changed the flywheel for a new one and went back to the Centerforce clutch...
Yes, bellhousing is dialed in to specs.
The input shaft to crank bushing fit has about 0.2 mm = 0,00787402 inch - not sure if that is ok. Bushing is brand new. Input shaft has same diameter on the bushing area as on the other areas.
We did not disconnect the sway bar yet - good idea - I think...
The surface of the clutch looked a bit burned at some spots and not 100% good - like some clutch friction material sticks out at some points - the pressure plate had some colored areas from heat. It was a brand new Centerforce clutch and we did not abuse it. But I think the chatter has put some...
That´s worth trying - thanks for the hint - I have another flywheel with minimal signs of use - will have it balanced & resurfaced and test that one as one of the next steps.
Hello everyone,
I have read many many threads about clutch shatter problems - also the one which has recently discussed in this forum.
The problem is quite similar:
- Take off in 1st gear is nearly impossible - extreme shatter, as if the dash would like to jump out of the car.
- Take off in...
BINGO!
The Ignition Timing Curve was the issue.
I have a MSD 8388 Distributor - which I bolted on originally with initial settings.
I did not have a clue that the curve would make that much difference.
Initial timing is now around 10 degrees - max 34 degrees.
Have first tried one light...
Thank you very much for the detailed explanations, tips and experiences!!!
I will first start with the ignition next week and at next opportunity with a 650cfm carb.
I mainly drive the car in the city, sometimes on the autobahn and 2-3 times a year on the strip. I think I will pass on...
Great - thanks for the quick and many replies!
Here some additional info:

Ignition is 12° before...
Hi everyone!
I don´t know how to continue at the moment.
I am generally happy with my setup - but the car could launch better and I´m not able to do a burnout. The engine just goes up to 2200rpm (converter stall speed) but seems not to have enough torque to spin the tires. Either the carb is...
