The Mopar squad cars are overlooked because most enthusiasts don't consider them "performance" models, even though they were often the quickest/fastest domestic sedans through at least end of M body production in mid-model year '89.
B bodies have a good degree of interchangeability and aftermarket support from '73-'78, and to a lesser extent, the similar R bodies through '81.
If you're restoring one of these cars, removing emissions control apparatus automatically makes your project a modification, instead of a restoration.
A '75 V8 police model (K in the VIN) would have stock Chrysler electronic ignition with a ThermoQuad 850 (1.5" primary) carb. Even with EGR and a vapor canister, the hoses aren't bad if routed neatly.
'84 models with the ELE 318 4bbl were probably the worst, with an altitude compensator added to the fender, with additional hoses. '85-'89 4bbl squads were slightly better, except '89 2bbl cars which had a vacuum controlled convertor lockup solenoid.
