I can still hear the ungodly --but beautiful-- sound of a ThermoQuad-equipped 440 being romped-on ; that vacuum sound was unreal !
Nick Winter is right about the engine colour . To add to his reply : just grab a spray can of Chrysler Engine Blue ( coll : "1972 Blue") from the auto parts store , as it's the right shade for '72-'83 Chrysler engines of all displacements ( 198 / 225 ; 318/340/360 ; 400/440 ).
Also : Cars destined for California were sans the *dreaded* Electronic Lean Burn computer . In its stead , a full compliment of smog devices were provided ( A.I.R. Pump , EGR , single exhaust / catalytic converter ) , whereas the Lean Burn cars were free of smog junk , as the computer was supposed to work favourably to reduce emissions (apparently , Jerry 'Bald Eagle' Brown was completely unaware of this).
Nice work you've completed so far !
