Kickdown linkage vs Lokar

The Lokar only comes in kit form as far as I've seen. Mancini's probably just has a generic picture. If you do a bunch of modifying you can probably make your stock stuff work. Like Zijmer said the high rise is a big problem. So is the Holley. It's not a 727 vs. 904 linkage issue. No stock linkage is gonna work with your setup cause it's totally different than a stock intake and carb.
