Hey guys, think you could identify these pistons for me? They came in an ls1 longblock I bought for my 68 Firebird
Im tearing down the motor for a rebuild, but found these under the heads....
Thanks
Just a quick clean up

If you have the motor tore apart that much already then I would just go ahead and take out the pistons. Then you will be able to know for sure what they are. Besides that block needs a good cleaning anyway.
