how much for a 1969 camaro build?

[Crazy03]

Well guys here is the question. I have been on this site for awhile now and have been looking at some very nice cars. I can do alot of my own work on cars and have questions about price. I either will buy a new z06 or biuld a 69 camaro.
My goal is to have a 69 camaro pro touring type vehicle. I already have the body I bought for 7k and will buy a big block with a 6spd for 10k. I know this is a broad question but what am I looking at price wise for a completion of the car. I dont want to go extravegant but would dyno mat the whole car, repaint, which my buddy does, definately suspension of some sort and a nice interior, meaning seats and a dash. I hope this is not a dumb question, but I dont really know where to start when it comes to an old school project. If the cost is crazy, I will probly just buy a 2006 z06 for around 60k. Any help would be appreciated and thank you for listening to my thoughts.
