3" length should be possible if you keep PE up for the next few years but if you work on girth too, it might take longer. I am trying to gain an inch in length and girth to get to 9" x 7" but according to The Visualiser - The Cock Comparison site the increase in volume is almost 60%!!!!
5+ years is typical for big gainers to achieve the gains you are looking for, good luck!
