I would do a second compression check, I'm assuming you had the throttle pinned open, and all plugs out. I'd also do the wet test and see how all those numbers match.
Personally, I would not tear into it , based on visual, if there is not a problem with performance.
Old school mechanics used to...
@EWheeler They are the stock 40 springs on 40 axles, I will take out another leaf before I cut the perches off, see what it gets me.
@pjohnson That is a great idea also, I forgot about it while working yesterday, I'll get a measurement.
Ok, I reversed the springs back to OEM order, long side to the front, taking out the bottom leaf. I had 3 1/2 inches of curve with the engine weight on before, now I still have 3. I think that will be fine, although I may find later I need longer bump stops….we will see.
The tie rod barely...
Side view. The pumpkin perch is as low as it can go without removing material off one side or both, and drivers side actually needs to come up 1/2 once to match it.
Here is side view, I probably can remove a leaf.
Mine has not been cut and turned. I read in FAQ I believe that an SM 420 clocks the TC enough that driveshaft angle is not a problem.
We will see, that may very well not work out in my favor. If so, I’ll take it all apart and cut.
