And the 318 isn't a cop motor. https://buffalo.craigslist.org/cto/d/1977-dodge-royal-monaco-blues/6676719244.html
From what I understand a "Cop Motor" was anything the ordering department ordered, there were a lot of Slant 6 Powered Cruisers in the Cities. Most of the 1976 NYC Police Lemans were 250 I-6 Powered, the ones used for highway patrol were V8 Powered. My 71 Catalina Freeway Enforcer does have a 455 in it, but the standard engine even for the Freeway or Highway Enforcer was the 350 2bbl. The Standard engine for the Light Duty Enforcer was the 250 I-6. But I understand the sentiment, if you are going to make a Blues Mobile Replica it needs to have a 440 under the hood!
It's common knowledge that the Mounties ride Moose, if you don't stop they use the moose to stop you.
Mopar cop cars were ordered as "police patrol" or "police pursuit" packages. The "patrol" package could have been a 225 or a 318 then. The "pursuit" was generally 400 or 440. In the Vehicle Order Number (VON) which is the set of numbers above the sequential build number on the fender tag, if that starts with a "K", that indicates it was part of a batch build for police or government use. The second digit of the VIN would also be "K"...but not always!
"It's got a cop motor, a four hundred forty cubic-inch powerplant, made before catalytic converters, so it runs good on regular gas. It has cop tires, cop shocks, cop suspension. Whaddya say, is it the new Bluesmobile?" *lights cig with a Zippo* "Fix the cigarette lighter."
