spark plug guide
Ok I know this is a stupid question. Who has or how to go about getting the correct spark plugs for the application?
I have a customers bbc corvette with a 502 BBC with ported world products heads. I have a set of plugs that came out of it but don't know if they are correct. I understand how toi determine heat range etc but is there not some deal with plug depth etc?
Also am I supposed to use resostor plugs with resistor wires?
