My boat engine is a 5.7LX, Thunderbold V ignition, newly remanufactured, with bran new vortec heads. I plan to install new plug wires. Should I install high resistance wires (500 ohms/foot), or low resistance wires (270 ohms/foot) ?
Tanks, Bob
 
The original engine had flat valve lifters and regular heads with MR43T plugs, and this new engine has roller valve lifters and new vortec heads an uses M43LTS plugs
 
the last set of OEM wires I had were more like 1000 ohm/ft.....using MR plugs.....

I doubt it will matter from the engine's performance factor....
