Removing 1967 273 Dipstick Tube Without Damaging It?

How do you remove the dip stick tube on a 67 273 block without damaging it?
It can't be pushed back from underneath as it bottoms out in the block and is not accessible
Thanks

From your picture, it looks like the oil pan is off, so you can drive it out from the bottom. I had to do this very task on a 360 today.

I took some pictures of the task and the tool I made for it in the past. My tool is similar to the suggestion of using a screwdriver or a pushrod, but I made my "tool" using a 5/16" bolt with the threads cut off,and the end ground flat and perpendicular to the shaft.

Place an 11/32" box end wrench on the bolt, in case it gets stuck, to knock it back out. Insert the tool in the inner hole through which the dipstick enters the oil pan. Using a small hammer, for better control, tap the tube out.

Light, precise taps, while holding the bolt shaft to feel for anything not moving as expected, are better than heavy taps. Some side pressure on the shaft might be needed if the tool is not catching the edge of the tube well.

This tube was tight in the 360, but it only took eight or nine taps to knock it out, with no damage to the end of the tube.
