Yes.
It is probably a broken valve spring.
To install 305 heads on a stock 350 Chevy engine, you typically need push rods that are approximately 7.8 inches long. However, it's essential to verify the specific geometry of your engine setup, as variations in components can affect the required push rod length. Always check with a mechanic or engine builder to ensure proper fitment and performance.
Chevy did not make a 350 in 2001. The last 350 was built in 1999.

To remove a bent fuel push rod from a 350 engine, first, ensure the engine is cooled down and disconnected from the battery. Then, remove the necessary components, such as the intake manifold and any associated parts, to access the push rod. Carefully extract the bent push rod, and inspect the lifter and related components for damage. Replace the bent rod with a new one, reassemble the engine, and ensure everything is properly aligned and secured.

Cam bearings, Rod and Main bearings. That will be all of the bearings required to replace when rebuilding a 350 engine.
You can put grease on the rod and gently push it into the block. the grease will hold it in place for a good amount of time.
The rod should be 5.75 inches; assuming the correct year, size, and stock cam, fuel pump, etc.
5.7"
Sounds like a rod bearing. Time for a rebuild job.
Just turn the engine over while you are pushing on the rod with your finger until the rod goes up in the block and starts to come back down then stop, and install fuel pump. Turn engine by hand. Put a ratchet and socket on the balancer bolt in the middle of the bottom pulley. Turn it that way.
