Talk to The_Raven or see the post by berettaspeed a few treads down on turbocharging your 2.8. The best mod you can make to your 2.8 is a 3400 top end swap from a FWD car.. that will bump your compression up and it flows just as good as a stock SBC. You can buy a cam for it from the aftermaket with costome pushrods or use the roller cam/lifter and guides with a little know how. But again...this is costing just as much as your typical SBC swap or 4.3 swap.
As far as bolt ons..besides the headers would be the 3.4 camaro top end swap as mentioned($35-70). Try some 1.6 ratio rocker from a early 3100 power fwd car (free-20)(do this fit iron head???). Ram air is as close as your going to get to forced induction without skipping your next insurance payment(free-$40). This is still maybe 15s. But even the 305s can just muster 15s.
