We are talking about a smallblock Cobra, right? To me it's a no brainer, It should only take about 2 hours max to pull the thing ASSuming you have a hoist. I'm with Mr. Fixit on the plastigauge, not very good. And yes, every engine that has main knock that I've fooled with usially needs crank work. Think of it this way, what if you crawl under there and find a bad crank? You would have to pull the engine anyway.
