Ha! I had the same curb. Filled it in with 4 bags of Sakrete Concrete! Made all the difference in the world.
Off the top of my heads, my mods are Steeda Progressive springs, 20mm wheel spacers, Magnaflow Street exhaust, Barton shifter, Mishimoto intake tube, Hurst type white shift knob, jacking rails, 50th anniversary. Tail lights, Coyote badged trunk panel and one of the best cheap mods was the the covers I put over the sun visor airbag warnings.
But that hood of yours, oh man how I have hood envy!
