Larry-if it is grinding going into reverse, the input is turning or trying to turn. Since you've adjusted the clutch different ways, I would think the input may be tight in the pilot bushing, or the input is bottoming out in the crankshaft. Is it a Lakewood bell housing? Did you check the bell housing bore runout? A mis-aligned bell housing will also cause the pilot to grab in the bushing.

Thanks Wayne, The Bell is a Quicktime, that I corrected the runout to under .005", so it's good. The input shaft doesn't bottom out in the crank, I'm sure of it. I have a mopar pilot bearing in there (torque converter register), and it fits just fine on the input shaft.
I understand what you are saying, but I just can't seem to figure out why the input shaft is still turning. The clutch is a McLeod Dual Disc RST organic face.
In all forward gears, life is fine. Actually, better than fine. I absolutely love the clutch.
Reverse is the only area that I need to figure out.

Like I wrote, I tried that numerous times. Put it into a forward gear and then to R. I've tried letting the clutch out a little in a forward gear, let it out in N, and then try R. I've double clutched N and then into R.
Every time, I get a slight crunch. Not too bad, but I'd like to get rid of it.
Maybe it's just this dual disc clutch dragging a little on the floater plate? But if that was the case, wouldn't it grind a little going into first gear at a dead stop?
I'm not 100% sure it would. IIRC, the A833 has synchronizers for all forward gears, but not reverse.

Hmmmmm...funny you mention idle. I've had an issue where my idle is too high, and I'm out of adjustment on the 2 carbs. So I know I must have a vacuum leak somewhere. That's an issue that is next on the table. Not a huge leak, but enough that I can't get my idle down below 1200rpm hot right now. Maybe that's keeping things spinning too much ![](/ubbthreads/images/graemlins/1343795-scratchchin.gif) I've disconnected the only vac port and it didn't change anything. The carbs are not leaking, so it's probably in the top for my cross ram or even the ports sealing to the intake. What do you all think?

Larry-since you have the adapter in the torque coverter register, you need to make sure the input diameter is .747 diameter all the way down to the taper before the spline area. Often they were not ground all the way to the taper, and are .010" to .012" larger diameter for the last 1/4" inch or so.
