    Default JE Pistons BBC 540 + .030 over size 548 inch 4.530 bore JE part number #257966

    Have a set of these JE's i have maybe 3 hours run time if even that. this was Blown on E-85 .. i had a rod bearing start to fail and 1 piston got scratches on the skirt and i would not use it again , Block in that Cylinder got deep scratch as well so i bored it too .060 over and bought all new pistons.. 1 other piston did get scratch but i think it will be ok with a light emerycloth touch up.. the rings are Hell Fire rings . for sure 6 pistons are good and 1 will need a light clean-up and the 8th i would not re-use but you could clean the scratch up and use if you didn't want to replace it .. i went to raised dome and put the engine in my Camaro so it got a fresh complete rebuild . pretty much everything swapped out in it AGAIN lol. i will post a pic in a few. my phone wopn't connect with my PC right now Grrr.. here is Summits site with specs for this exact piston to replace the 1 . https://www.summitracing.com/parts/jep-257966-1 .. 300.00 for all 8 pistons with Rings
