Wayne: I have seen and admired Adam and your and Owen's commitments to preserve him and his DNA. Any idea as to his compression ratio? And what is his redline? Has he been dynoed? (Adam's, not Owen's!) My question was more oriented to the production cars. I think the '55 300's went on sale on Feb. 10, 1955. It is possible Cad started production of their dual quad Eldorados earlier since it was the third year for Eldo's. They did produce 3,950 1955 Eldo convertibles--a peak they never exceeded. If Cad did come out earlier with a 270 HP engine, it would seem like Chrysler called and raised. Good for Chrysler and good for us, but I've not seen that little strategy published, if it indeed it helped drive the creation of the 1955 C-300.

It is currently in Owen's possession in New Zealand. There have been suggestions that other '53-54 New Yorker Pan Am race cars (Carrera Panamericana - Mexican Road Race) cars were dual-quad-equipped. My understanding is that race rules prohibited that (which is why Adam did not race). No others known to exist. Also suggested is the possibility a handful of '54 Imperials were dual-quad-equipped. None known to exist. Adam was the 5th to last '53 New Yorker for the model year. So Chrysler had dual quads in 1953. Estimated horsepower 315 with solid lifters, roller tappet cam, raised compression.
