Waco Cobra Club,
We are trying to figured out what type of spark plug to use in one
of our Cobra's, this car has a 351W engine with Aluminum World heads that were installed on the car about six weeks ago, some
of the plugs look as if they are firing good [white chalk look] but
3 plugs are black as if the plugs were not firing. We are trying to
figure out if the val's need adjusted, are could it be the plugs,
we're using AutoLite 25's at this time. At the time when the heads
were changed we had energizer rocker arm installed but didn't
change the push rod, we would like to go to a better push rod.
Three questions, any recommendation are comments:
What about the plugs, do we need to take a look at the Val's,
an about the push rods???we are thinking about comp cam 4130.
If anyone can help we would sure appreciate it.
