Hello everyone, looking for some advice on troubleshooting and which direction to go to fix the chatter on my 68. SBC 327, muncie m20, 10.5" cutch zoom flywheel and clutch kit, mild cam 222/222(i believe), dual plane intake. 12 bolt rear with 3:36 gears. a couple years ago I switched from a PG to a muncie m20. I sourced parts though here, parts swap meets and purchased new items. after the swap i had very noticeable chatter starting off in 1st and reverse. I chalked it up to a brand new clutch, pp and flywheel setup that needed breaking in and my 3:36 gears weren't helping. I dealt with it but had to rev to 2500 rpm plus to get rid of the chatter starting off. drove around for 1500 miles or so before I went to a unit where I was consistently deployed for three years. the car maybe got 1000 miles in the past few years. Stationed in Hawaii now and decided to buy a hydramax clutch kit to get rid of that long mechanical creaking Z bar and linkage and t would force me to drop the tranny and inspect everything to solve this chatter issue. today I dropped it and found many hot spots on the flywheel and pressure plate, also noticed the center portion of the clutch disk was slightly rough compared to the outter and inner edged of the disk. tomorrow ill grab calipers and measure the input shaft of the tranny and pilot bearing. from eyeing it with a tape measure it seems the pilot bearing has a larger diameter than the input shaft on the tranny. Tranny input shaft has more radial play in all directions than I like. when i installed the tranny i upgraded to the heavy duty front bearing. I suspect a few different issues....1st lower quality FW, clutch and PP. 2nd maybe I put too much grease on the shaft splines and it flung on the clutch assembly??? 3rd too much play between pilot bearing/input shaft. 4th its normal with my numerically low gear gear and cam? I would love to go the TKO route with the 5th gear but its pretty spendy especially shipping to hawaii. So im looking to solve this and move on so my car is more enjoyable to drive. with the symptoms and photos what do you guys think is going on an which cost effective direction should i take to remedy it. Thanks!
