As usual, just spitballin' here. I am leaning toward going with an adjustable valvetrain in the Charger. My 440 based 493 has the Mopar performance 292/509 camshaft and replacement stock rocker arms and shafts. The belief was that Ma Mopars line of Hydraulic cams were designed with mild lifts to allow the retention of the OEM rocker arm gear. Some say though that the ratio was intended to be 1.5 but has been known to vary, mostly to less than 1.5. This means loss of lift and duration, therefore power. I am considering a switch to the adjustable kit from Hughes Engines. Their kit is priced at around $550. This got me thinking: Since I am making the jump to an adjustable setup, why not consider using a SOLID flat tappet cam? My compression ratio currently is 10.73 to one. I have Edelbrock RPM aluminum heads with the 84cc chamber. They are not ported or modified in any way. 2" TTI headers with a 2.5 exhaust system. Edelbrock RPM dual plabe intake. Barry Grant 850 VS carb with 85/92 jetting. MP electronic ignition. 727 with 2500 stall. 3.91 gears in a 3900 lb car. Any suggestions on a cam?
