i have a ‘71 340 I bought a couple of years ago. Was told it was a “fresh”build. I pulled the valve covers and the oil pan, it was nice and clean inside so I put it in my car and ran it a bit. It always kind of annoyed me because I couldnt get it just right. I messed with timing, carb etc and still wasn’t real happy. I recently pulled the trans to overhaul it and decided I’d go a little further on investigating the engine. I figured I’d pull it apart and ck the bearings and was interested in...
