Hi Spectra 72, I have a 71 polara CHP. I still need the various equipment you've been discussing; radio and head unit, rear facing lights, siren, wiring and all the other switches for the dash mounted panel, etc. If you have any of the parts I'll be glad to purchase them and if you see any of the items listed some where let me know. I have my email listed for the forum members. I also need the mats. I can't see pictures on the forum that have to be clicked to go to a hosting site but I am able to recieve/open emailed pictures and I can send my pictures by email but unfortunately can't post them to the forum.
Krautmaster asked about a plate in the seat back to protect the officer. My seat does not have this item. The front and back seats are well built and the wavy spring support system is strong. Plus a secondary set of support springs is placed under the main four sites people would sit and come into contact with after a certain amount of compression. Monacos got the molded foam 60/40 front seats and our 71 wagon was comfortable with them. Also, with a girlfriend on a date, the reclining passenger side was easily the best feature in the car.
Also you wondered about the radio still being able to recieve, and they are. But some of the frequencies are different and you have to get the correct plug-in crystals for the frequencies in your area.
My car is still on the rotissorie so I've a long way to go.
A comment on the engines these cars had. Over the high HP years the factory made for our cars, '67-'68 HP's (Magnum, Commando) made the best low end torque with the closed chamber heads having the best squish/quench minimum space between the piston top to the flat area of the head. Typically ~50-60 thousandths and compression ratios above 10:1. The factory then changed to open chamber heads and kept the compression high for '69-'70 and so the horsepower stayed up as well but didn't have as much punch off the line. '71 dropped the compression and '72 even more. My '72 Road Runner barely had 8.5 when I measured and calculated it at tear down. Still good running engines but 1969 was the banner year with top speed.
Jazz, I'd really be interested in knowing more about the engine in your '66. The performance head castings generally weren't availiable until '67 (other than max wedge in '64). If you take your valve cover off, check the casting # and date. Pre '67 heads were smaller valve and port size. I know, I've plumbed the H20 jacket trying to port them. Maybe you could also check the machined top pad and cast dates and cast numbers on the block.
As I posted before, I'll be disassembling the cop motor that came with my car. And I'll report on it. I don't expect to find anything out of the ordinary. It is not the CHP motor. It was stated to have been a Nevada State patrol of the same year. It has the normal small balancer. It has an unusual (not regular production line) oil pump cover that does not incorporate the spin on oil filter mount and has in/out threaded passages to go remote. It has the stock normal (small) oil pan. Anyone wanting pictures, I'll be glad to email them. Ron.
Hi guys, No metal plate but its a darn good idea!!!! The equipment is still available but finding it is tough. Classic auto battery has the original style battery, original auto interiors had the cloth for the CHP cars cars, I bought enough for two or three cars (never know what might be found), the lights are available thru John Dorgan at Beacon Sales (sirenman1.com), most of the rest is hunt and peck until you find it. I did re-crytstal my motorla (I worked in a radio shop) to receive local low band traffic, around here its mostly Dept of Trans and some aux traffic stuff. I thought about pipeing in a scanner over the speaker but it would have to be a crystal type (and they are huge), FCC and local regs prohibit use of a programmable scanner in vehicles.
As far as opening it up, I have run it at the local dragway a few times when I make changes. A couple years back I went way out north with a friend who is a state trooper and opened it up a bit...pleasantly surprised at the power/performance. It rides very well and gets going pretty quick for a big fat car. The CHP cars had Holley carbs that were specials, it took me alot of time to track down the part numbers and parts to rebuild it. I expected that typical Mopar Thermo-quad roar...its close to it but a little muddy sounding, it definetly pulls harder than the TQ.
The air cleaner has the vacuum operated trap door which opens under hard acceleration. Sounds boss.....heres a little FYI, the cop cars had true dual exhaust which exits off center at the rear....and they had Hemi Mufflers. What a sound they make!
"Black-C" is that a 70 or 71 Monaco 2 door in your profile?? I had a 70 Monaco like that...absolutely gorgeous cars, mine was a 383,black interior, auto but what I loved most were the reverse lights up high in the corners...5 slots that would light up......awsome.

The TTI exhausts systems with DynoMax Super Turbo mufflers sound as close to the hemi mufflers as you can get - a veritable symphony!
I ran dynomax ST's on my 69 Charger...I loved them, I ran into ACCURATE EXHAUST inc by accident and found they had what I wanted for correctness but was custom inside (better flow and a bit louder). OFF topic sort of..still on the exhaust side, I just put Flowmaster American Thunder cat back on my 2010 Camaro...it sounds very 70's.
My Monaco had walker glass packs as far foreward as possible and pipes all the way out to the back...that was a nasty system on the 383.
