8 weeks to greatness?

Well T-folk I have paid the money and I have 8 weeks till I go on a cruise. I want my body to look as good as possible. My plan was to bulk up a little for the next 4 weeks and then cut down the last four. My plan was to do GVT for my bulk phase and probably a 5x5 to cut down using the fat fast diet. I bought a four week supply of 4 AD-EC that I will take on my cutting phase to save as much muscle as possible. I will be running sprint intervals for my Cardio. Right now I am 5’9" 158 lbs. and 9% bf and 21 yrs. old. When all is said and done I am hoping to be at 170. Is this realistic? My diet will be great. I was also wondering if maybe I should stretch my bulking phase to 5 weeks and 3 weeks of cutting. My metabolism is pretty good and I will only eat about 1300-1500 cals cutting. Any advice would be great.

if you bulk then cut right away often times results are undoin ala cutting then bulking right away. i would do several weeks of maintenance before cutting.
