Replacement Clutch
Could it be that the engagement is to high up for a diaphram pressure plate ?
no; you set the freeplay same as usual , about 1inch at the pedal.
The Factory had a 3-finger B%B clutch which required a good strong left leg to release it. To make life easier, Chrysler installed that O/C spring to assist your leg during the down stroke, and to reduce the leg-power required to keep the pedal down.
But with a diaphragm clutch, leg power with the correct pedal ratio, is much reduced, so normally it is not required. Furthermore, if you don't remove it, it has happened that at higher rpms, the pedal likes to "stick" to the floor and it then remains disengaged, sending your rpm to the moon. So then, the HD O/C spring that comes on 340s and bigger engines, has to be removed to prevent that. Tis does NOT mean that you cannot run a lesser strength spring. I, for instance, run something I pulled out of my spare parts bin, that I think came off a 318 car. I don't run it for the usual reason, but for feel; I like the modulation feed-back that I get with it. And I installed a rev-limiter just in case. So far so good since 2002 or so.
Now as to pedal ratio, ALL the slanty parts are different from the 318 or bigger engines and the hi-perf engines add the HD spring and brace.
Bellhousings have specific mounting positions of the inner-end ball-stud, and when or if you mix and match parts or adapt parts, it can thro the Z-bar out of it's sweet-spot operating range and angles. The clutch fork comes in three different lengths, for three different size bellhousings. If you accidentally get stuff mixed up, you get these kinds of problems.
Since you already have one car that works well, I suggest you go look it over, taking pictures, and compare yours to it, to see what may or may not be causing your particular problem.
Finally if nothing shows up, it sortof points to a super HD clutch, a wrong pedal ratio, or dare I say it; a limited-strength left leg...... which is sometimes related to the pushing angle/ seat height, or a pinched nerve in your azz often due to the operator sitting on his wallet.
As for the pedal ratios there are two. Like said, one for the 9.5 inch clutch (slantys and 273s) and another for everything else. The difference is in the fulcrum placement on the pedal arm. There are a couple of threads on FABO showing the differences. I'll see if I can find that for you; hold on.
Try this;
is there a difference between 6 cly and v8 manual pedal assemblies?
Hyup works for me.
