Sorry about my lack of thread experience,just noticed from the comments it was an old thread but still active as I see from your remarks. I was only interested in the compression after a stock set of LS6 pistons would be installed in an open chamber head like a 781. I have a chance to get a set cheap as well as the 781's but am afraid the open chamber will still leave me with less than 8 to1. Just asking and I'm assuming I'm the OP your talking about(I'm getting emails that your talking to me but can't see it from your comments) sorry if I'm not.
