Looking for experienced opinions on removing k-member.

Here's the "other way around. It IS NOT really that big a deal to block up the engine, and drop the K out the bottom, with the engine still in the car. I did mine on my hoist, but so far as the engine, I used blocking, padded by old rags, jacked on the frame rails and fender aprons, and used multiple motorcycle type tie down straps as "hoists" to work it down or up into place.
