That 337 is a very nice intake. It acts alot like the M1 intake, very good mid range and upper RPM. There was a time where that intake and the 2.14 / 1.81 MW iron heads were avaliable at the same time. A good customer on mine used this combo on his 505ci. pump gas engine and made a very nice sleeper.
....there is nothing like driving my 1968 Hemi Dart around town and having people looking at you like you're nuts!!
