Default single, dual

if you compare the factory style intake (dual plane) with vacuum secondary
carbs the dual quad makes more power, this is dyno proven and confirmed by
time slips on the track dating back into my racing log since 1979. the dual quads being sold as factory reproductions (holleys) suck to say the least
they are poor quality castings that require constant fiddling. the distance
between the two carbs on the factory\ blue thunder intake make outfitting
other style carbs quite the project because of the secondary side of the
fuel circuit. if given the choice i would take the less hp single carb, because
the majority of use will be street and the extra couple tenths gained on the track isnt worth the hassle of regasketing the carbs and cleaning the needle and seat because of crappy gas that we all know and love, get the eldeb. single
4bbl dual plane and put a barry grant carb on it and bypass the leak down
and casting flashing problems associated with the holleys....

just my two cents
