Its the same penalty as now -.6
Basically under this penalty box the 318 bore is the standard. And so is the 3.31 crank.
So right now the 340 gets a -.5 Basically cause of bore crank is the same. Now a 360 is slightly under a 340 bore so it would get i would guess -.3.
So the leaves the stroke to get to the -.6 we are already at that means the stroke is worth -.3.
Thats just guesses thought could divide it -.2 block and -.4 crank.
