951 Piston specs...
I ordered a custom piston set from Diamond Racing back in February and I have yet to receive them. I emailed them today saying that if they didn't show up I'd be taking my money back. On that note, they had the specs on hand when I ordered them but now that I may go doing this order on my own I need those specs.
Also (while I have an informed audience) I was planning on staying with the stock compression etc... I have had the Darton MID wetsleeves installed and I need to go to a larger bore. I'm looking to go to a 104mm bore, bringing me to a 2.7L. So my second question is: Should I stay with the stock compression, or is there something to be gained by changing things around? Thanks

lower compression will allow for higher boost with safety.

lower comp will make it weaker off boost and stronger on boost and vice verser all personal preference keep it between 7.4 and 9.3:1

Thanks for the help. The pistons finally came through from Diamond so luckily I didn't have to do it all over again.
