4BBL for sure . . I know I was stating "Rochester" carb . . but then I went back and added "Quadrajet" to clarify.
You know . . I'm not dissatisfied with the power with the 2bbl and tired old engine . . .however, I have a
desire to get good performance and increase FE where I can. Long after I make a decision on carburetion and
other aspects of my engine overhaul, I will have to live with the fuel consumption. I realize a large square iron box
hurling down the hwy delivers poor gas mileage . .
But whatever can realisically be done to increase the FE and maintain good performance . .
that's kinda where my head's at.-
