65' truck future 472 caddy swap

[Enginewolf]

Hello forum I'm new here, recently I've purchased a 1965 gmc 2500 fleetside, I've got a 1968 caddy 472 big block that I plan to swap into the truck and just wanted to see if anyone else has done this swap before (I know they have, by no means is this swap new) and was just trying to get some advice, pointers and helpful knowledge to steer me in the right path to completing this swap. Thanks everyone for any info given in advance
