Re: vortech charged 351c
i have a whipple supercharger mounted on a lightly modified 6/71 manifold.
Just the bolt holes needed readjusting for blower placement
It really depends on whose manifold you are using as to the height it will give.
i have just over 4mm gap between my leads on the dizzy cap to the blower snout
My advice, mount your blower and manifold, then see if the dizzy fits. Don't spend any more money unless you need to.
