What If Build Ideas...for Land Speed Racing

i'm currently working out the bugs in my intercooled intake design . but the bottom end and heads are ready to assemble , trans is ready . still need an od unit , quick charge rear end is on hand , just need some tall gears for it . oh ya the most important part is the rear rims , 18x6's taylors made rims are the cream of them . but taylor's not producing land speed rims for some reason . they are a lot more work than nascar rims . so i'm in need of the rear rims , fronts are not an issue , just 15x4/5 steels .
