Hello! Putting the finshing touches on my 512 build for my Challenger. Mostly street, maybe couple trips down the 1/4. Some engine info: 440 stroked to 512, 440Source kit, OOTB Indy EZ's, 511 lift Comp, 10.5-1 comp, NGK plugs, FireCore wires, stock 6pak set-up. I'm using the Mopar elect dizzy, orange box, 4 wire ballast. Just wondering if this ignition is the best? I've read most use the MSD style. I've put a lot of $$ in the engine, and want the best ignition system too. What's the thoughts? Take care! Jeff
