I read years ago that NYPD ordered their police vehicles in the 1960s with 6-cylinder engines for fuel economy reasons. Apparently the thinking was they were never used for high-speed pursuit in NYC and a bigger engine wasn't required. Can anyone confirm that?
The Police cars were available in two packages - the Pursuit Package and the Patrol Package. The Patrol engine options were a 225 or a 318, while the Pursuit Package could be had with a 383 or a 440; this in B- and C-body cops. A-body cops were rare, and were exclusively Patrol Package cars. This, being the early '60s through the late '70s. It changed in the '80s with the F- and M-body cops, which could have had 225, 318, or 360 engines; with the 360 making up the Pursuit Package.
So, yes, the 225 was likely the engine in many NYPD cars.
I read all this back in the days when people read books and magazines, pre-intewebz; so, no, I do not have a link.
To reiterate from another thread about cop cars, there is NO such thing as a "Police Interceptor" package in ANY car other than a Ford; as that is a trademarked name for a police car package built by Ford.
Oh, and sixtysix fury, a funeral car is a HEARSE, NOT a "hurst", which is a performance shifter.
