hi folks
on my list of small items to-do this winter (
oil cooler, better springs) - i'll swap out the spark plugs. i was running 'stock' autolite plugs from a lincoln with a 460 in it.
i have a 521 (429/460), aluminum ford super cobra jet heads, msd 6al, and fuel injection.
any suggestions on what you all are using, somekind of "splitfire" fancy plug?
im sure i can squeak out another 1hp per cylinder
