Drain Plug for FE Oil Pan

[dandascott]

I have a stock 427 S.O. with original high capacity oil pan (with windage tray). Now, I am looking to add an oil temp sending unit in the drain plug. What I am thinking of doing is getting a new drain plug and drilling and tapping for the sending unit to thread into the drain plug. Then when that looks how I want it, I will replace the old drain plug.

Does anyone know what the threads are for this ? The engine is full of oil, so it is a pain to take off and check if someone has a good idea.

Thanks in advance.

I am not sure that would be a very good idea. I believe your capulary will be out of the oil part of the time giving you a false reading plus you really don't want anything else hanging down below your pan. Take the time to weld a bung on the top part of your oil pan that you can screw your sending unit into.

Clois gives good advice.

... and you might want to pull the pan before drilling a hole and welding a bung.

i am sure with the fe you are running a remote oil filter, why not plumb the
sender into a tee at the adapter plate on the side of the block?

Thanks for the suggestions. I have plumbed a "T" off of the remote filter. I measure temperature for the stock "oil" light and pressure for SW gauge. Since, the stock light for a 67' Fairlane is just a HOT/COLD light and I wanted more data I added a SW oil temp gauge. I could rob that location and not use the "HOT/COLD" light.

I did not want to cut and weld on the oil pan. It seems very hard to do in place and I defintely don't want to pull the engine.
