And so it starts... 340 build

And another handy tip for you novice engine builders.
This is a “sacrificial” 6 inch 3/8 drive extension. It is a good fit for the plugs at the front of the block. A little more Indian head gasket and drive them in a bit. They should be counter sunk.
There is also a trick mod to be done here later. A small drill hole on the driver side plug to spray some oil onto the timing chain for that little extra oil insurance that can only help during high rpm runs. A drilled a 3/32 hole in the plug. I think that was a bit big when I was done. Installed now. Coffee break.... LOL
(Not that this engine will, maybe, I think. OH! I don’t know....)

I don't put squares in round holes because it puts four point pressure and distorts the circle out of round. To each his own.
I set them into the holes by hand and then use a 2 lb sledge and pop them flat in.
Others tap them for threaded plugs.... either way a cam plate covers them.

They sell freeze plug glue... but you dont have to use it. The indian head is good for intake gasket fitment, thermostat gasket, oil pan and valve covers. Gaskesinch by edelpuke works the same... as pematex in the can does too.
