A few tricks, first and foremost to get the specific answer with the specific given information of 88 Cubic Inches
-A cubic inch is 16.387064 cubic centimeters, (CC)-
you multiply 16.387064 x 88(your Cubic Inches of motor)= 1442.061632 (CCs)
Or if you know that you have a 1.4 Liter Motor, as according to your factory build OEM Manual, you can take the decimal point to the right three times to equal 1400 (CCs) .... so 1.4(L)=1400(CC)s -This is of course not the engineering spec but rather A close estimate usually given to the consumer.
approx 1584cc
the 1340 evolution motor by harley davidson is 84cc.
The Harley Davidson 110 cubic inch motor produce a conservative 80 horse power
48
3.8 liters
68
325 cca
50 cubic inches is 819.35cc
80 cubic inch or 1340 cc
50mm
Since each cubic inch is 16.387064 cubic centimeters, you can just multiply 16.387064 x 80 = 1310.96512 (CCs) So Eighty Cubic inches is about 1311 CCs, and yes that's a big motor, about 1.3 Liter. I think I once had a Ford Escort (car) that was powered by a 1.8 Liter motor, but that was a 4 cylinder.
