I had a pretty fresh 355 sbc. Started with a popping/misfire. Led me to find pulled rocker stud......then 2 loose studs maybe 50 miles later.....then trying to troubleshoot noticed it didn't want to idle and when I shut it off I noticed the fan would stop IMMEDIATELY, like it had brakes!! Found metal in the oil filter and pulled it for teardown.....wiped out 8 cam lobes....ruined all the cam, main, and rod bearings. Rebuilt it all over again.

Inexpensive and relatively quick to cut open the oil filter. Rule it out for piece of mind.
