Opinions on 4 speed with OD
The clutch is what breaks transmissions. You have to have some way to control the application of the clutch. If not you’ll break it.
and that is why after the first time it happened, I did the following.
1) I swapped out he CF-ll disc, in favor of a factory 340 disc. They don't last as long but they are much more gentle.
2) I reduced the clamping of the CF pressure plate by spacing it away from the flywheel. It slips a lil off idle, but when the flyweights come in, it's all good. This makes for very pleasant and relaxing drive-aways. Starting off, with 3.55s is more or less a "dump it and go" routine, almost right off idle.
3) Every time I get in the car, I remind myself; this transmission is a 3+1.
4) I practiced NOT shifting into Fourth, EVER, unless I was going on a cruise; 1-2-3 STOP!, lol.
In the end, I pulled it out.
