I'd be willing to bet that the front-most spark plug is located real near the same distance as the rear-most spark plug. I'd guess the center of the spark plug hole -- Dan?
I would tend to agree. And admittedly this is a non-issue for 99.9% of existing LSR cars.
Would it be reasonable to define the fore/aft location of the front most sparkplug for transverse in-line or V configuration engines as being near a vertical line that cuts through the center of the head to block mounting surface?
That is sort of a long-winded way of saying "somewhere close to the spot shown in the circle on the photo of the CBR600RR engine in this photo."
I am just trying to avoid a debate in impound (if I ever get there) some date in the future, where someone says, "hey your engine location exceeds the setback rule."
Dan's comment about crank location of the OEM engine. . . .That seems like a reasonable idea.
In any case, I guess I need to come to terms with building the car as an Altered . . . .
