Thanks Commando1.
That is what I thought, but there are so many different sites on the internet that list it differently.
Thanks a lot.

Somebody gets it...:toilet04:
That explains things better
As we all know, the 440 was introduced in 1966. There were two versions that year. The first was a 350hp version. The second, introduced for the 66 1/2 models had 365hp.
This second version is a bit interesting. It was labelled by Chrysler as a 440TNT, but wasn't the full out TNT that was introduced for the '67 model year, as it still had logs.

I have the TNT dual snorkel air cleaner. so it has 365HP? This car was purchased in August of 1966.
There seems to be very little information available for the 365bhp engines. As far as I am aware, the only differences are the dual snorkel filter, and a (dual) 2 1/2" exhaust until the muffler exit, when it goes down to 2 1/4".
As part of another project, I recently dynoed a "near enough" 365, and found that it made the same amount of hp as a 375hp engine, but had a better torque curve.
You should be able to tell from the VIN number which engine was originally fitted.

The fifth digit in the VIN is a J, indicates 440.
Here is the complete VIN CM23J63207436
Ok, I will check it later and get back to you.

I think you meant to say 'UNDER rated'?
Quite correct. Neither the 350 nor the 365 made anything like that. The 375 hp versions that came later didnt make that either.

Make sure we're not talking apples and pomegranites here.
Don't forget that up to 1970, Hp raing was taken under ideal conditions on the test stand at the flywheel. That was THE accepted way of rating advertised HP and a whole lot of cheating and lieing went on with a wink-wink nod-nod from everybody. Back then, the 440's WERE absolutely under rated on their HP.

1966 plymouth 440 commando was rated from the factory at 365 hp. according to my original owners manual.
