The lines on the 72' Imperial are so clean and honest, it all works perfectly at that height....begs to be left alone IMHO.

I'm recalling it as a 300 more specifically. With a 4 speed to boot.
Or more likely I'm confusing several cars in one big mish mash...

Yeah, but if your gonna bring it back to life its not original, a Hemi would be nice, in an original wrapper though

I agree completely. That's why I bought a 73.
I did hear of that story and also a story about 1 of none Chrysler 300 that left the factory with a Hemi.
[h=3]The Chrysler 300 with 440 Hemi (by Curtis Redgap)[/h]
| 1970 Street Hemi | 10.28:1 compression | |
|---|---|---|
| Horsepower (gross) | 425 @ 5,000 | |
| Torque | 490 @ 4,000 | |
| Carb | Dual 4-barrel Carter | |
| Intake/exhaust duration | 284° / 284° |
One of the spinoffs from the A990 full racing Hemi program that was built and tested but not produced was the 300 Hemi model engine, meant for the 300 letter series sport sedan
cars. 440 ci was obtained by boring the 426 block to 4.32 inch from the 4.25 inches. The 3.75 inch stroke remained the same. 
may have been slated for around 455 or more. It was never dynoed, so figures are not available. Of the many 426 Hemi engine variants this was the only one that got two main bearing cap bolts.Following are some of the specifications from the white paper, written for John Wehrly by Bob Rodger, father of the 300 letter cars, and by product planner Robert Cahill.
Mr. Wehrly had joined Chrysler in 1962 and quickly moved up to become supervisor of racing engine development in 1971. In 1964, Mr. Wehrly was heavy into the Hemi development for the Daytona 500. In 1965, after NASCAR moved to ban the Hemi and Chrysler staged a complete boycott of the NASCAR circuit, Bob Rodger and Bob Cahill, sensing that NASCAR would not ever relent, moved quickly to push the 426 Hemi engine into a regular production model available for the street to anyone with the cash to buy it. The letter follows:
Description: Because of continued requirements for an ultimate performance drag strip and street usage type engine with expanded usage, the following change is the engine lineup has been agreed upon after discussion with the affected areas. Please release a hemispherical combustion chamber
engine for "B" Series with the following general characteristics:- Intake manifold to have two four barrel carburetors.
- Cylinder block to maintain cross tie bolt bearing caps.
- Cast iron exhaust manifold.
- Solid lifters are acceptable but not preferred. [Hydraulic lifters were not achieved until the 1970 engine - ed.]
- Pistons - forged acceptable and thermally controlled preferred.
- Manifolding and camshaft to be designed to give the best highs speed power possible while still maintaining a reasonably drivable vehicle for summer and winter.
- Automatic and four speed [manual] transmissions required. 4-speed to receive development priority.
- No air conditioning required for "B" series.
- Limited warranty is acceptable for the "B" series.
The above letter was dated January 6, 1965. On January 12, 1965, an engine production letter was issued for the A102 engine. It listed all the items needed to bring the race Hemi engine to specifications for use on the street.Mike Sealey wrote: There is a 1966 Chrysler 300 out there with what appears to be a factory-installed 426 hemi, something most historians say never happened in C-bodies. According to Chrysler historian Jeff Godshall, last minute reconsideration was given to discontinuation of the letter series 300 after the L in 1965. A tentative plan was drawn up for 500 1966 300-M models powered by the 426 hemi, but was withdrawn when marketing research suggested there might be a problem selling even that small a number for the price

When Stan mentioned a Hemi 300 I immediately thought of a 70'.

It's said it was originally planned to put a Hemi in the 300 Hurst but due to assembly line production at Jefferson this was discarded due to installation problems in regular production. Probably had no sledge hammer at hand, like Hurst for their Hemi Darts.

If they were going to put it in a 300 thats the car to do it to
1970 Hurst 300
 | |
| Production | 1970 501 produced |
|---|---|
| Body style | 2-door coupe 2-door convertible |
| Engine | 440 ci (7.2L) V8, 375 hp (280 kW) |
| Transmission | 3-speed Torqueflite 727 automatic |
Hurst 300
The Hurst 300s were all 2-door and shared a white and gold paint scheme similar to the Oldsmobile and Pontiac Hurst models of the day. The scooped hood and trunklid (with a molded spoiler) are both fiberglass. All Hurst 300s had satin tan leather interiors that were straight out of the Imperial and could be had with column- or console-mounted 727 automatics. All came with the 375 hp (280 kW) 440 cu in (7.2 L) 4-barrel TNT V8 engine. Road tests clocked one at 0-60 at 7.1 seconds with the 1/4 mile in 15.9 seconds. "Not bad for a 4,100 lb (1,900 kg) aircraft carrier", they claimed.
Of the 501 units sold, one convertible is documented having been used as a Hurst promotional car and another is believed to have been dealer equipped with a 426 cu in (7.0 L) Hemi, also, a convertible.

1970 Hurst 300The 1970 Hurst 300 lacks the single-letter suffix of its forbears and appeared five years after the last Letter Series Chrysler, the 300L. Many automobile historians do not include the Hurst 300 as a Letter Series model. The concept of the car, however, does fit with the Letter Series cars, as it was a high-performance variant of the luxury 300, built with the input of aftermarket parts manufacturer Hurst Performance. Only 501 units are believed to have been built.

If I recall correctly they have the real one. They did a spread on the owner....who happened to own a 70' Hurst 440, and the HEMI car as well. I'll look and see if I can find it and post the pics. Some people have all the luck.
Rumored............one factory Hemi 1966 300M (prototype) from Detroit for one of the exec's. It was never titled. Other than that, not that I know of. No factory Hemi 1970H's. One dealer installed Hemi 1970H. And maybe a few privately retrofitted.

It's known among 300 fans as the "'66 300-M(onkeypuzzle)".
