Hi, I found this forum today while trying to research a motor I'm looking at buying to put in my 1949, F1 pickup. I've been offered what the guy is calling a Cobra 5.0 . The serial number on the block is: F6LE6015-AA It also has the markings that indicate it was made by TEKSID. I'm going to look at it tomorrow. Apparently it had a dirty oil issue and snapped a rod, resulting in a little cylinder damage (requiring a sleeve job.) I'm looking for opinions from anyone here and also some guidance on what I should be looking for when I inspect this engine. I currently belong to the Ford Truck Enthusiasts forum and there are a TON of smart guys there. So I'm hoping and am pretty confident there a lot of smart guys here as well!
