A dual snorkel air cleaner does not mean the engine is a TNT. Anyone can put an air cleaner on it sometime in its life since new, even the dealer that sold it new. TNT engines have a different camshaft and different hi flow exhaust manifolds very similar to the B and E body cars used with magnum and commando big block engines. Also, all TNT engines will be stamped HP on the front pad of the block, under the AC compressor area. No HP stamp, no TNT. That is the way it is and the way Chrysler did it. Also, ALL TNT cars had dual exhausts from the factory. Which means a different gas tank, slightly narrower to allow room for the other pipe. A real TNT car in 1966 is very Rare. That is probably why no one sees the K in the vin# ever. I have heard of a few but I have never actually seen one in person in the 25 years I have been chasing these rigs. In 67 and up the TNT became more common and was rated at 375 hp because of better heads with larger valves. If you had a car with the TNT engine code in the VIN# the only thing that will denote is that engine came in that car. It does not mean the car will have Discs or a console etc and vice versa, a console car with discs does not have to have a TNT. You could order a 4 door wagon with drum brakes manual steering and a TNT if you wanted to. A couple years ago I looked at and nearly bought a 1967 Polara convertible with bucket seats and a console, 440 magnum(TNT), 18 spline hemi 4 speed trans, Dana 60 sure grip rear axle, manual steering and AC. Very, very weird optioned car but it was the real deal!

Hi all: I have a 440 TNT '66 300 conv. It has a "J" in the VIN. My car came with a 440, twin snorkel air cleaner, disc brakes and the consol, everything that is supposed to make up a 440 TNT. Even the template on the air cleaner states TNT. I duplicated the worn original when I restored the car. You can see it in the club web site stories. It is my opinion, based on various inputs, that this car is indeed a 440 TNT, 365 hp. I have never seen a "K" in all the 440 TNT cars that I have competed against over the years.
