Re: Piston ID help
I just looked in my Sealed Power catalog. It looks like those pistons are the ones they used in Vin K Chevy truck engines from 1991-1996. You will probably have to cc the dish to figure out what pistons you need. That looks like a pretty big dish, if I had to guess I would say at least 15cc Those engines were only 8.5 to 1 so I am betting you will need a pretty small chamber head, somewhere around 58cc ? to get the compression where you want it. I doubt that you will find a published piston cc spec anywhere. The Sealed Power replacement part number is H580CP
Hope this helps,
