'72 340 question

[jmartin99]

I am putting together a 340 for a '72 Challenger Rallye.

Okay, where does the oil pressure switch go?  In the hole on the top of the back of the block?

Also, There are two threaded holes on both sides of the block.  Does anything go in these other than threaded pipe plugs?

Thanks!

Oil pressure switch is in rear near distributor.

The ones in the side of the block are to drain the coolant out of the block and only use plugs to keep the coolant in and the oil sending unit goes in the hole in the back of the block like was stated above.
