Trying to figure out a plan of attack on my new toy

just picked up today a 73 dodge dart that was advertised as a 318....well i get home and decode the vin and it says it came with a 383...well i was all excited but i was told the engine was swapped...so i went under the hood and looked at the stamped numbers on the block...
comes back as the following

4179930 – 1975 – 1993, 360 LA-series small-block

so i bought this car as a fixer upper not running..they said it needed a carb...i am not worried after 50 plus years things change...so i got to make all this right...this block has a carter 0-2361 carb on it ...what i dont know is did they change the short block and reuse the 318 stuff or all 360 stuff...so how would you all attack this to make it all a go...i dont even know if the carter 2361 is the right carb for the 360...do i need to look for the part number on the heads? will that change anything...just trying to get focused on a plan of attack...any guidance would be appreaciated...
