The regulator location and plumbing that Mr. Roth has on his car is, in my opinion, the best way to feed a side outlet Quadrajet (assuming that is what he uses). However, the best situation, again my opinion, is to use a late model, front outlet Q-Jet with the regulator mounted directly in front of it, using both outlet ports to a y-block, then to the carburetor. The 75' and later Q-Jets have more float bowl volume because of the aneriod cavity and the front outlet eliminates the severe 90 degree turn the fuel must make before the needle & seat in the side outlet carburetors. You can and should do some work on the side outlet Q-Jets to help the fuel turn the corner. This set-up is hard to do on Chevy combinations in Stock because of the thermostat housing but the carb spacers and taller manifolds in Super Stock make it doable. Hope this helps.
