tons of questions

I have an 82 camaro. the engine in it came out of a 68 malibu elcamino that was rolled. the engine i believe is a 70s block. the engine was rebuilt right before the accident. it ran before it was pulled from the 68. now i need to redo the timing so i can get it running. is there anybody who can walk me through the steps of doing this. ill admit i dont know much about timing so if u can dumb it down a little itll be appreciated. thank you!!! i also pulled the old carb off it and put a rebuilt never ran edlebrok on it. i may need to adjust that.
