Is there any major performance issues with relocating the coils? I know the closer the coils are to the plugs the more efficient they are but will moving them cause any issues in a high horse power application?

 

Nope. Stock wires are roughly 950ohms per foot, most aftermarket wires are 50ohms or better, so essentially a stock wire is equivalent to a 19 foot long aftermarket wire.

 

That's some good math! Thanks for the help.

 

the only "bad" part is you cant buy off the shelf wires and usually have to make your own (MSD has a kit or you can piece one together). But the engines do look a bit better with the coils hidden out of plain view. I ended up shaving the mounting bosses off my valve covers and painting them.

 

I wish I thought of shaving the valve covers before I painted them. That would look a lot nicer. Where did you end up putting the coils?
