Heh, on the subject of Scoobys, I once saw this, which confused me, not having any idea what EG33 meant...
Those 180 headers are cool, too. The "180" refers to the 180 crank degrees between ignitions in cylinders in a given bank. A cross-plane V8 is uneven within each bank, which is why it burbles. A more accurate comparison for the sound of 180 headers is to that of a flat-plane V8, which is essentially two interleaved (flat-plane) four cylinders. Note, though, that the GT40 still has a noticeable cross-plane sound, because of the intake (although in that configuration, with exposed ITBs / individual carb' "barrels", you'd do well to distinguish a
You could also get 180 degree intakes for cross-plane V8s, too, for the complete conversion! (Except most available 180 intakes would sound very similar on a flat-plane V8.)
The cylinder pairings in the intake are identical to those in the 180 headers. 👍
