I am trying to install my mechanical fuel pump on my Chrysler la 318. I can insert in timing cover no problem going straight in. If I point pump arm down I am unable to tilt back and align securing bolts without a lot of force. I think may damage pump arm. However I’ve read and in the manual is says it should be inserted at an angle under the cam. Should I rotate crank to tdc on a certain cylinder? The pump arm seems like a heavy spring. Level of difficulty/finess? Thanks

Turn the engine over 90 degrees and see if it helps. You might be able to see the cam and turn it over till the high part of the eccentric is at 12 o'clock.

Pnora is correct. You’re probably trying to compress the pump arm spring while the arm is on the lobe of the cam. If you rotate the engine you should get off of that “fuel pump lobe” and have an easier time installing the pump
 
Sorry I’m a rookie in this field. If I remember the timing cover only covers the timing chain (top) and the nub that protrudes of the camshaft (bottom). Rotating the crank would not change anything between the block face and under the timing cover where the fuel pump inserts
 
Ok, in all do respect you haven’t seen the rest of the repairs in progress
 
Oh yes it will, turn the engine over till you can easily install the pump. Put some grease on the tip if the arm.

You are thinking wrong. Google some images and maybe you will figure it out.
