Wasn`t that weld up thing done to an m1 ? I have a 1200 cfm throttlebody, w/ 8 injectors in it, I don`t think it would work very well w/ a dual plane. The thing is actually bigger than the interior of the carb pad on a perf. rpm. Hood clearance is tite, top of the filter is about 3/8" from the bottom of my 6 pack scoop,w/ a drop base bottom plate. (hence the interest in the torque 2), it`s lower than an RPM. Am thinking about getting hughs to rework a torquer 2 w/ their street n strip porting. the $$ ain`t there right now tho! LOL
