I got these from a friend who I swear told me they were 580cc Delphi's. I want to know 100% for sure so I can get accurate duty cycle readings and correct offsets. They all seem to have different numbers hand etched in them...

 

Man does wires look scary as he'll

 

got to get them flow tested to be sure. they are definately delphis

 

Those are stock wires... simply have the plastic clips removed. Not sure whats so "scary" about them.

 

Ive been told they are 580cc's by the person who bought them. They show 13 ohms on the meter too..
