Question-
« on: September 05, 2015 - 12:49:51 AM »
What size is the oil plug behind the filter plate. And not the one that holds the filter plate on.
 I know it is not N.P.T. thread pitch. Close as it comes is a 3/8.
My motor is ready to go on the Dino and I need this plug ever so bad

Motor is a 1969 340 out of a Dart.
Its just a little 340 with a miss

Not my motor but think this is the plug I am looking for. It's the hole with the fine threads.

Is that a 3/8" nptf plug. I see it fine thread.
I got to get one cause the guy building my motor does not want to mess with it.

It was a standard but an odd ball size. I forgot what they called it. It's was smaller then 3/8 npt. Not by much tho.
