I have a '62 with a 383 stroker (just got it running last week) and Tremec TKO 600 5-speed, with standard front engine mounts and the supplied Tremec rear mount. Over the three years I have owned this car I've evolved from a 327 and Muncie 4 speed, to an upgraded 327/ 320 HP with the Tremec. I installed a resurfaced 11" flywheel and I installed new front rubber mounts three years ago. Since I've owned the car I have used three different clutch discs (10 1/2" and 11", all street quality) and have experienced bad clutch chatter, especially in reverse. The chatter has not gone away with any of my engine / transmission / clutch plate iterations. Note that this chatter occurs at idle speed and lessens at higher engine speed.
When I test-drove the 383 with the hood off last week I noticed a pronounced movement (rotation) of the engine that corresponds with the chatter that shakes the entire car. It's worst in reverse and also in first gear when starting up an incline. But I also get very minor chatter when downshifting. No engine movement / no chatter.
I've thought about temporarily making solid front mounts to see if the problem goes away, but I know that's not a solution. I've considered shortening the sleeve inside the existing mounts so I can squeeze them down tighter. I've looked for poly replacement mounts and cannot find them. I've also considered installing a rack-and-pinion system so I can use side engine mounts.
Before I go to extremes, I wanted to see if any of you experts have any other suggestions on minimizing the chatter. While driving with the hood off I see a definite correlation between engine movement and shaking. Therefore I conclude that I need to tighten up the engine mounting in some way.
In the past two summers I have put about 2000 miles on the car each year. When I installed the stoker this winter the flywheel looked like brand new. Do I simply need to get some mileage on the clutch and flywheel in order to reduce the bite between the clutch plate and flywheel? Any suggestions or advice from your own experiences will be appreciated.
