383 piston ID - 04/15/11 01:23 AM
Need some help identifying some 383 big block pistons. They are stamped .03 on all of them. Not .030 but .03 which is the first time Ive seen that but Ive only had one other mopar motor apart in my life. The cylinders look pretty fresh no ridge, some evidence of cross hatches etc.
Looks like maybe they balanced it from looking at the crank and rods.
I know it ran, I heard it and drove it onto my car trailer.
Anyway I pulled it apart cuz it had been sittin a few years and it looks like a fresh motor but I can only find 265 stamped on the inside of the skirts and .03 on the head and thats it. No other markings. I can tell its not a forged piston but I was hoping to find out some kind of information on them.
My next step is to see how far in the hole they measure and until then Id like to know what they may be or if anyone has seen something like this in a big block mopar.
