The engine has no expense spared which is obviouse from the $ spent on that killer manifold.
Fastest one i ever saw went 8.00 on spray.I have a bud with 2 untouched sets and thought real hard about doing the sets he had on my spray motor because if the 3/4" deck thickness.
I think personaly i made the right choice with the w9.
Either way this w7 should rip it up @ the track.
