hi i've been on this site a while done alot of looking but cant find much about piston specs for a d 15 . im going to have a spare carbed motor and was planning to do a mild build over time . higher compression , performance cam and headwork etc. unfortunatly for me i cant find much allong the lines of specs for various stock or after market pistons and rods , i can do the math involved to find the combo id like performance wise but no specs . help and or links would be a huge help . and youre opinions and experiences appreciated. thans you all are great
