Performance Converter

I've read previous threads on the subject, but looking for fresh information. I'm building a 408 stroker, 10:1 Malhe pistons, Molnar forged crank, H beam rods, with a voodoo solid roller cam, 279/285@ .050, .585/.600 LSA/ICL 110/106. 727, 8 3/4 with 3.73 Auburn SG. Tires are stock size 215/14's. I'm more interested in which companies I should contact to have a custom converter made for my application. Coan seems to be a highly regarded company. Pretend you're spending my money......
