Basic 318 info needed

My vote is for the 88 engine. I swapped 318s in my 87 ramcharger for one that was an 88. Has the factory roller cam, #302 heads and the pistons were .018" on the hole compared to the 87 motor that was nearly double that. I rebuilt the 88 completely stock and the power difference is night/day to the non-roller 87 motor.
