Hey Folks I hope you can help.
I have a 1982 CJ-8 with a rebuilt 4.2 (22 K miles) using a Holley 7448 carb and an auto trans.
The valves sound like i'm making POPCORN when I get on the highway and pull a hill.
The timing is set at 5 degrees (it was WORSE set at 6).
I've added the "Juice Box" upgrade (big distributor cap and 8mm wires and big output coil).
Is there a test you can recommend to make sure the HEAD isn't messed up ?
Any ideas or suspicions ???
I'm worried that if I keep driving it the way it is.... something will go BANG !
