What to buy next for my 68 Camaro

[camaro2nv]

Im marking the next stage in my project. Im 95% sure my boat is sold, that frees up 17k. I havent started a build sheet yet. I just didnt want to get discouraged by it. So far I have bought
Morrison rear clip complete with rear end, gearing ect.
Modded create LS2
Computer and harness
Wheels/tires
Custom Sub frame
Shockwaves
Solid body mounts
I know the 17k isnt going to finish the car but I would like to get it on the ground rolling.
Seems like every time I go to buy a part the price changes. Like the T56 Magnum trans. Its been posted for 3k by a vendor and when I go to order the price changes to 5300.00. My point is its hard to gauge what the next round of parts will cost. So if some of you that have been through this could post thoughts it would be great!
Heres a want list so far
T56 Magnum kit
Z06 brakes with two piece rotors
LS drive kit with AC
