This is a really common event on 383s. The fuel pump pushrod wears down.
Can you remove it with a piece of wire and gob of chewing gum? A magnet?

I was able to finess it out with the telescoping magnet and a pair of hospital forcepts. I measured the pushrod and it is only 3.21". I have heard they are 3.25 new is this correct? Can't seem to find one instock at my parts stores. They all need to order them. Does that .04 make a difference in the operation of the fuel pump or is it the cam lobe is worn down.

That worked out good. I was expecting you might have to cut it in two to take half of it out on the inside which would not be fun. There's NOS ones on eBay for $18.95 +$5 shipping. I'm wondering if all the NOS MP ones are fine?

If mushroomed just forget it leave it in there--pull the pump, cover the opening and go electric--be riding in an afternoon with no hassle--way too much trouble to get a "shroomed" one out.

I have the original motor for the car on an engine stand and pulled that rod out. It basically fell out when i took off the access cap. This pin is 3.22 long. Im going to measure the pin travel in both blocks using a dial caliper if I can. The pin out of the 71 block looks to have some wear on the end where as the one in my original motor is smooth and dont those pin spin as they go up and down to keep the from wearing to quickly? Does any know for sure what a new pin lenght is???

I am going to say that .040 is not enough to prevent all fuel flow. Quick check, be sure the fuel will come out of the line to the tank, a rag with an air gun to give it quick blast of air into the tank will put a bit of pressure on it, and fuel should flow out of the line to the pump.. Test the pump manually by moving the arm, it should squirt a couple of feet. If all that is good, reassemble and loosen the line to the carb, check for fuel./ stuck float.. I just had a to start a car that was sitting for 10 years, couldnt get fuel in the engine, the float was stuck. Last possible thing is the cam can be worn out, not moving the arm. .

I was surprized too but when you rolled it on a flat surface real slow you could see it. Even the shaft had shinny spots opposing each side. New pin and pump installed and now it shoots fuel out of the pump when I turn it over.. putting everything back together hope to have it running tonight. Thanks for everyones help this has been strange for something so simple.....
