Need some help making my budget work

[softballnrd27]

I have a set budget to do a drivetrain/chassis upgrade/rebuild for my 85. What I ultimately want is a "nice" street/strip truck that I can jump in and drive where I want and also take it down the 1/4 mile and back home. My plans include a LQ4/9 swap backed by a th350 and 9" rear. My budget is right around $7000 total. I have priced out several different routes and I want some "help" to get me in the right direction. I plan to rebuild the motor so it's fresh, rebuild the th350, and get the 9" built. I have to rebuild the front suspension bc it is horrible so I figured a poly front end kit and the right lowering components. I need a notch for out back and some new shocks all around. The fuel system is what is kicking my butt right now. I can do it with the stock 87 style tank and basically stock components for right around $375. I want to run a cell in the rear but that "system" costs around $900 complete. I can't see how it would be smart to run the stock style system only to upgrade to a cell later ultimately costing more in the long run. I don't want to cut corners but I also don't want to waste money. Sorry for the long post but I got so much crap going through my head right now and need some help form my fellow truck "nuts".
