Looking for some help with the type of plugs that I should be using in my 350. The motor is 1969 model out of a car.
thanks

I have a 1968 350/350 hp and I have found that the best plugs for my application are Champion RJ12YC. I have used others but prefer the RJ12YC. Depending on your heads and application you may find others to be equal or better.
