Father-Son 1974 Duster Project

probably a good call on the new lines ... curious why you want to use the HEI distributor ... unless you've already got it or can get one cheap ... I would use a stock Mopar electronic setup ... I like them , but's thats just my opinion . I had a 340 years ago and I let somebody talk me into "upgrading" to an aftermarket dizzy and ignition . That was a waste of time , money and energy .
