Is a hipo distribtor/coil necessary?

I'm running a 273 Commando - Holley 600cfm, Lunati .515/.525 cam, port n polished stock heads, Edelbrock RPM intake, duals w/ h-pipe & 4.10 rear. I estimate 285hp - 300hp. Last year I accidentially turned in my MOPAR hipo distributor as a core for a stock distributor that I purchased. I put the wrong distributor in the box and was running late. I also. switched out the 'flame thrower' coil for a stock coil. Anyway, I put 500miles on this setup and I don't notce any power differences. She pulls strong and redlines @ 6000rpm. Was it a waste having the MOPAR distributor on the motor? Should I replace the stock dist. & coil? The reason for the swap out was actually a misdiagosis of a fuel delivery problem, bad fuel pump and needle & seat.
