My 350 is not firing on 5 and 6

Any ideas Thanks

Cylinders 5 and 6 are next to each other on the distributor
cap,check inside and outside for crack or carbon track.
Good Luck! hope this helps!

And or pull the valve cover to see if cam is opening valves.

Lesson, check the nieghbor kids work before assuming, switched wires and lost clip. Thanks, Great forum!!!
