F Motor Oversize Pistons

[ZachA]

Hey Guys!
I’m midpoint on an engine rebuild of a ‘71 F.
My bore is worn so that standard will no longer fit. I can got to a 0.020 flat top but they are unobtainium. Spectre has 4 in stock but I need a full set of 6.

Does anyone have another source I can tap for pistons and rings?

We’re willing to go to 0.020-0.040. I’ll take any full set with rings.

Any shared resources would be appreciated!

I am replacing my F engine because cylinder #6 had a leak and caused some rust in it. I rebuilt this engine over 20 years ago, but it has less than 10,000 miles on it. The pistons are flat top .030 over. Since I am probably going to scrap the motor, you are welcome to the pistons. You just pay the shipping. Here is a picture of cylinder #6 to give you an idea.

The rest of the cylinders are in good shape. The rust is mostly from the head. I you are interested I can pull the pistons out and take a look at number 6 and send some pictures.
