It’s exactly what it sounds like - build up your DD. But there’s a catch. You have to be willing to do all of the work by yourself. Here’s what I would ideally want to do to my GMT400.
LM7 swap, injectors, FMIC, eBay 76 trim, full exhaust, parking light duct, HD rear, post-02 4L60E with Corvette Servos, 3/4 drop, DRs, custom Diamond steelies with some insane offset, electric fans, big rad, flares, and an MSII.
