You'd have to check with darton to see if they are safe to bore beyond that for a NA application. You could offset grind the crank to Honda B series crank journals. That would give you about a 78.5mm stroke. You have to be careful doing this as it will make the crank stiffness decrease due to less overlap between the crank journals.

100 x 75= 3.534L
102 X 75 = 3.677L
100 x 78.5 = 3.699L
