Cool Arggggg!!!!!

Went to "pull" the sending unit on the new 350 motor. But first....

At the direction of a new friend on the list here, I understand that the sending unit for the temp meter in the '83 was set up for the smaller diameter (3/8" threads) sending unit. Using the old (bigger) sending unit, the temp reads at 260 almost immediately...Which I know is wrong.

The larger sending unit I want to remove (1/2' threads) is in the block on the driver's side near the exhaust manifold, as I see is the traditional spot.

So I pulled the sender out of the old 305 motor that's now on the stand, went to the hardware store and got an adapter (3/8" > 1/2" threads). Teflon taped them up (picture).

As I said, went to pull the sender out of the 350, which is now in the truck.

1) 15/16" deep socket, 3/8 drive, 2 extentions to get around the brake lines, etc.

2) No go. Move to 3/8 *breaker bar*. Nope.

2b) Pipe on the end off the breaker-bar. No again.

3) I didn't have a 1/2" deep 15/16ths. So I adapted the 3/8 to the 1/2" breaker. Threw away the pipe. Grabbed a fat handle off of my 3 ton floor jack. Put the sweat to her.

4) Nope.

5) Pulled out the electric impact..."Oh No!!! Not on Brass......"

6) Ratta=tatta-Tatta-Ratta-Tatta-tat.

7) Nope.

8) Lost some Brass. But a 15/16 still fits....A little less "bite", and some shiny flakes around the work area.

9) Sender's still in.

10) Question the '83's parentage.

11) Realized that was not fair.

12) Quiestioned the parentage Previous Owner of the 350 motor.

Can I screw in to the threads at the plug at the top of the water pump?
Any other place anybody would recommend?

I'm hot. I'm tired, and I'm sweaty. Can anybody save me?
