Chevrolet: my chevelle, cam shaft, drum brakes

Question
hi, i just purchased a 70 chevelle. it's a malibu that someone tried to clone. i'm an amateur when it comes to mechanics and i've had know luck with questions about maintanance seeing how the car is 36 yrs. old. i know the car has a bad cam shaft and needs to be replaced. problem is, i'm no mechanic and i don't know what size the block is. i also have drum brakes on all four wheels and would love to know how to convert the front end into disc. i'm 19 and desperate for help, so i need professional help, can you help me out? (i'm an amateur who knows only how to change oil and rotate tires, so if u explain something, you'll have to brake it down!) thanks,

Hea- well its a good year. is it a big block or small block ? can you get me the motor ID #s. I think you should get a tech. book for that year car- it will help you 10 times over. as far as the cam you must think of what type of a motor you wish to have . You can get a change over kit for the brakes,  there are a lot of them out there.
