bump.
Anyone had this done? either 49 or 50mm? Been pondering what to do while mines in storage. Been thinking of DBW but if I do that, then might as well do this too. Want to retain 6 throttles.
I have a fully build head(CNC, OS valves, 286/278 cams, etc etc still running squish), and a Greddy old school intake with port matching.
Head bench flowed 300cfm. Wondering whether bigger throttles will give me any gains. Makes 563kw.
