The volume of the cylinders when the piston is at it's lowest point in travel is the "size" of the motor. A 4.6 Liter motor holds .2L ( or 200 cubic centimeters ) less air and fuel mixture than a 4.8 Liter motor.
48-2 = 46
48
-46 + 48 = 2
-94
22/46 = .48 = 48%
LCM(46, 48) = 1104.
2 + 46 = 48
No it can go to 48 but not 46.
45 + 46 + 47 + 48 + 122 = 308
45 + 46 + 47 + 48 + 107 + 108 = 401
t is 96/46 = 48/23
Those years are very similar. Positive identification could be done by serial numbers.
