Almost every dyno shootout involving a 6 pak goes like this; run the 4bbl, jet the 4bbl, toss the 6pak on run it as is & call it a day, & the 6 pak usually actually puts out
more at certain points in the curve, but has the "kick-in" sag somewhere in said curve.....max output is almost always near = or better. Yes it is more difficult to tune, &
ultimately it's worth is in the coolness dept., but they run perfectly fine dialed in. Costs lots more $$$$$ to do right.......................
