Speedmaster vs Edelbrock air gap intakes

So which 408 had the speedmaster intake and which 410 had the Eddy RPM intake ?? LOL
The Blue Print engine has the Edelbrock on it.


Guy i race with has your 408 in his Duster, been testing/ racing it for 2 seasons, car is setup to race pretty well. Best has been 11.90’s at 110 thus far. Should run way better than that.
IDK if this is it of what your thinking about @318willrun
