Mopar 284/528 mechanical camshaft

I'm running that cam in my eddy headed 360. Same intake and carb, 2500 conv w/391's. Car idles @850-900 in gear mild lope... but crack the throttle and she goes!!!!!!!!!!! I picked up 15-20 rwhp swapping this cam over the comp xtreme energy 274/491 hydraulic... My car is a street car first, strip second. Best time to date 12.75@106
