Need to know the year, so WE can answer your question right. You will need to ask your question again with that info. Thank you.
i know on a 75 Chevy scottsdale with a 350 it is 35 thousandths
There are 8 freeze plugs.
yes
Should be 1 5/8".
Sometimes 8, sometimes 10.
Front, back, and both sides.
That depends on what type of heads are on each, and the year it was built.
If you mean the freeze plugs......they are located on the bottom side of your engine. They are round and are about the size of a half dollar.
