I have the 292/.509 purple cam in my 440 in my Charger. Loved how it ran back then and how it sounded. There may be better cams out there today but back in the day, that was a great go-to hyd cam!I had the 280° mopar cam 1 cam smaller than the 284 cam. It ran good. Now replaced it with the 292 purple cam advanced 4° @ crank. It runs real nice too! The sound is music to my ears!
