shocking problem

[thump16]

Okay, My starter went out on the truck this weekend so i replaced it with a stock one which is two sizes bigger than the mini that was on it. So it sits about a 16th of an inch away from the header. I also rerouted all the plug wires because it has hedman long tube headers.
Well today I fired her up to go to work and I get this loud thudding noise coming up from the carb/intake manifold when I gassed it. So I start checking all the wires and I put my hand on the dist cap and I get zapped. It is an MSD set up with remote coil. Should I check for a cracked cap or is it a deeper problem. It only sputters if I go past a certain rpm range or try to drive it.
