Really? I ran dozens of '74-7 police cars through my yard over the years and they were all 440 cars except for the '76 Darts. Maybe we didn't have them here in Ca. Now in the 80's....yeah we had a bunch of 318 Dippy police cars with the 360 top ends in them. We also had 2 '78 model Monaco's (B-body) with 360's. Did your 318's have 360 parts in them too or were they straight 318's all the way? I guess you could order just about any combo you wanted. I understand that there were some slant 6 police cars made too. I suppose if you were on a small island, you didn't need to outrun the bad guy because he really couldn't get far anyway. Might as well save on gas and maintanence costs.
