Rear supsension question

[nogaroa4]

I've done searching on this site and other sites, and I'm trying to make up my mind on rear suspension. I know ultimately it will be my decision, but your feedback would be great.

I originally planned on doing a flip kit on the rear but I soon realized untill I was done buying new shackles, flip kit, new spring, new shocks I would be up around how much a 4 link would run

Then I looked into a 4 link that would cost around 700-800 when I was all done

I want the truck low/very low and I'm trying to build this truck on a budget.

I would also like to eventually put a motor in that would be around 350-400hp

Any suggestions on which route to go
