i also had that same dream when i was 17. but it took me 13 more years to actually do it.
i have and am still building a tubbed 69 camaro with a 396. it cost a lot of money, that's why it's taking me so long. like chris said, it's alot of time, correct measurements, the correct tools, and patience.
for what you want to do, you can buy a frame kit for that year camaro, set you back about 1000.00, then the 15x14 wheels, for a pair, about 400.00, tires and tubs,another 500.00, rollbar, 200.00+, trust me, it adds up quick.
i don't know how many times i wanted to sell mine and just give up.
but in the end, it's a great final product, i love how mine looks. don't let me give you the wrong impression, but if your going to do it yourself, it's a lot of time , hard work, and money. here's the site where i bought all of my stuff, www.swracecars.com
have fun and let me know if you have anymore questions that i might be able to help you with.
