Had it been an issue Cobba? I knew years back they were only 10.5.

No just a lot of misconception, I and many others on the forum where under the impression they where 11.5:1. A couple of emails to TTS went unanswered on this until I questioned them on their pistons advertised on ebay and photo of a slipper skirt piston on their sales ad.
At least I finally got confirmation from tts and changed their ad so now this can finally put the myth to bed.
