I have just purchased a 1968 327 with a 3 speed manual . The engine and tranny are believed to be original with 105000 miles on them. Whenever I am engaging the clutch (1st or reverse) from a completely stopped position the car doesn't seem to respond well and the dash/cowl area vibrates. When I am on an incline (such as while I was trying to drive the car onto the tow dolly the vibration is considerably worse. Whenever the clutch is fully engaged however, there is no shaking evident even If I slow the car down to as slow as it will go at idle, and then give it gas it responds fine and takes off without shaking. This shaking is similar to what one might expect to feel while trying to start in second gear from a stand still.

Thanks for reading!

 

best guess, warped flywheel and or preasure plate

 

Other possibilities: worn out clutch disk to go with a torched flywheel face, busted spring in the clutch hub, worn pilot bushing in the back of the crank.

 

Yeah, I'm gonna go with warped flywheel as the #1 offender.

I have long ago given up having flywheels "resurfaced." Metal gets a "memory" to it. That's bad. It gets warped due to heat and pressure. Machine it dead-flat when it's cold and it'll STILL be pretty well warped up again when it's hot. It can drive you nuts. New metal is the only around this.

Put on a new flywheel (and a new clutch with a fresh pressure plate and pilot bearing, since you don't want to do this job twice) and you'll be amazed how much smoother it is. Night and day.

 

can this problem occur with my 97 Ws6 as well, becaus ei have the EXACT same symptoms as carrolte, sorry to dig up archaic posts... just looking for some help..

 

Yes, late model cars will do the same thing. I prefer to replace the flywheel along with the clutch install vs resurfacing the flywheel.

But a clutch job will most likely fix your problems.
