    Default Help with PR4 Pistons

    I have been tearing into an engine i just purchased and it is a GSR block. After pulling the head i notices it had PR4 0.8 Pistons in it. If i am correct those are LS pistons. Can anyone give me an idea of what the advatage to these pistons in a GSR block is? If anyone has any info it is very much appreciated thanks, Tyler
