I'd suggest super stock springs and a stock K frame since it's a "budget" build. If you were are planning on getting in the mid 500+ HP range I'd suggest cal-tracs. After market k frame stuff is nice, but pricey too. As long as you can find stock stuff cheap I'd go that route, if you can't than save your $$ for an aftermarket k frame. Strut front end would be idea, but would take some fab and $$, but not really needed unless you plan on going fast.
