I have a 1940 Chevy 4 door sedan. I installed a 235 6 cylinder from a 1957 Chevy car. The engine sounded really good before it was removed from the car. I then installed the engine in my car. The engine ran really good in my car. Then I got busy with other things and parked the car in the barn. The car sat for about 4-5 months. Today I started the car and there is a tapping noise coming from under the valve cover. What could be wrong and what can I do to fix it?
Thanks

Does the tappet noise decrease as engine warms up? Solid or hydraulic lifters?
 
Did you do an overhead? Probably just a valve or two out of adjustment.
 
I’ve never had the motor opened, it supposedly has 5000 or so miles on a rebuild

If it didn't have this problem when it was parked, I doubt it's an adjustment issue.
I'm guessing it has hydraulic lifters and the ones left holding the valves open during the the 4-5 months it was parked, probably leaked down.
You really need to identify what kind of lifters are in this engine first, and go from there.
