Distributor to engine install HELP!

318 4bbl. I had the engine running,really rough. pulled the intake and dist., andrebuilt the carb. I thought i had it all marked. Put it all back together and now it sounds like I''m not getting spark. Engine will turn and turn, nothing. i know it's getting fuel. What is the easiest way to get my dist. roughly clocked correctly? Set the engine to #1 TDC and get the rotor pointing in that general direction? Thank you! :banghead:
