    Arrow Piston I.D.??.

     



    The engine is a 350 1996 one pc rear seal four bolt main with a windage tray.It was bought in a donor Astro van for my Ole Yellar project high top Astro.The seller told me it was a crate engine with 30,000 miles on it when he purchased it out of a chevy pick-up truck.I am wanting to turn it into a 383,but would not do so if it is already over by .030 or more.I don't own a dial-bore-gauge.I got the casting number off the piston I took out and it says it is part number 101282 and is a four eye brow with a notch towards the front.I did a google search and didn't find any info.Please help me find the size of that part number piston if you can.

    Thank You,

    Gary
    Good Bye

    Maybe Tech or Jerry has dealt with that part number before and will chime in.Of course anyone else's input is welcome.
