At a minimum check the adjustment one more time. It is common for the push rod to not get seated in the socket correctly and when it slips in there will be excessive slack. It can also happen that the lifter will separate when the retaining clip get pounded out from improper adjustment. Then you get some extra parts floating around the engine. On a real bad day the top piston will jam in tat slot in the lifter bore and get struck by the lifter as the cam pushes on it. That's the end of that engine.

I've tried the speed run over time and distance. Just doesn't pump up.
Loud as ever!
