What kind of horsepower can you run through a factory style Muncie? Anyone out there running the Supercase set-up with an iron midplate,500 plus hp ok? Just for background I am hoping for 470-500 hp from a 30 over 455 but may try to get a little more if my budget allows. I was planning on the Tremec TKO600 but the Muncie should be cheaper to build. I am starting to gather parts and want to know if I am on the right track. Opinions?
