I think its a holden dizzy just made to fit a mopar. Not the same module as gm HEI but does the same stuff. The curve probably sucks in stock form I would play with lighter springs assuming they are accessable. The only bad thing is you might not be able to get the cap/rotor and module at your local parts store. Other than that re curve it and it should work pretty good. I got a big hei skip white ditributor for my ford engine. Works pretty good, springs seem way too stiff though. But it the Chinese parts look decent enough for daily driver duty.
