Should I begin assembly?

Hey all, I'm finally getting my 360 back from the machine shop on Monday and was wondering if I should start assembly or not. I'm asking 'cuz it might be 2 or 3 months before I can run it (still need a carb and radiator and need to rebuild or replace my trans). My worry is that the lube and oil might run off components in that time. So, will I be fine or should I wait to assemble? If fine, what assembly lubes and oil will stick longer? Thanks!
