Again, I suggested a mod because the work has already been done to make room for it. It would also give you great reliability and mileage. If you wanted power/torque out of it, it can bolt on a supercharger and it would make your 67 with the BB look silly. Something to be said for a car that could run a 11 sec quarter (or better) and then drive coast to coast with the air on while you carry on a conversation with your passenger at normal speaking volume. That's what "Pro-Touring" is all about.
