Wear on piston skirt

[morbius18]

Check piston to bore. Even with a perfect port, if the clearance is too much it will shave down the piston skirt.

I know what you are saying, but that intake roof and floor is choppy. Perhaps it’s not it’s first rodeo. I’m sure you see the giant plating crack as well.

I managed to squeeze a .004 feeler gauge between the piston and bore. If you mean that extremely large crack looking thing, it was a hair on the cylinder.

Looks like an eye ball looking at me through the port

That is funny how it looks like one.

The port has been dropped and beveled. The line on the previous pic was 78-79 degrees. I finished it up and hot washed in the sink. It's too cold to go back in my unheated shop to degree it again.





It looks slightly curved, but with a light in the intake, it breaks open evenly.

Heres a pic of a meteor piston in my 281. 3-4 tanks maybe, play saw only, piss revved pretty much all the run time. Pic isnt great but machine marks are there right to the bottom of skirt. Intake was a bit flat and the bevel on the bottom is peened over pretty bad, but nothing like the first pic in this thread.
