I always ran a PL3001 in that car. The 3001 is the equivalent of the Motorcraft FL-1A, AC PF2, Wix 51515, etc. which used to be the standard full-size filter on loads of engines back in the 60s. The bypass pressure, gasket diameter, and thread pitch are all compatible with the 14670 filter, but you get a larger filtration area by a bit more than a factor of 2. The caveat is whether or not it will physically fit because its both longer and I think a bit bigger in diameter than the 14670.
If either of the Mopar filters you're talking about cross-references to a PL3001, then I'd recommend you use it (or else just use a 3001) ;-)
I found out that the Mopar 5037836AA oil filter was developed in a collaboration between Dodge Viper engineers and Wix. My dealer had one in stock and it is quite a bit heavier than the standard 1090 Mopar filter. It also has a different inlet hole pattern, different top base plate, and looks different inside from what I could see peering in the center hole. Physically, it is the same size as the 1090 - so it is not as big as the FL1a. It has a white can with Mopar and Viper imprinted on the outside.
