I just read an article (Muscle Mustang or 5.0) on a TB test on a supercharged engine and the 70mm TB made a couple more HP then the 75mm TB. Doesn't really make any sense and I know magazine tests our worthless in the first place, so take it for what it's worth.
Just remember trap speed isn't everything. Using DR's for the first time my trap speed went down from 102.x to 100-101.x but I dropped my et's from 13.9x to 13.6x.
