Making a budget for an LS swap in my 69 c10

[Kook87]

I want to get the most bang for buck as everyone does but need a little help. I have read a lot of different opinions on this topic so here goes. I want an LS engine swap. Don't really care what direction I go to start with. LS1, LS2, LQ. What I am looking for is hopefully 500rwhp all motor. The least amount of machine work as some truck heads require. I know LS motors are more money up front than the LQ motors but it seems the LQ motors need machining to equal the LS motors. All info appreciated and taken into consideration.
