Come to find out the outside of the balancer had walked. A new balancer was installed and the timing marks are now where they should be.
Come to think of it, I had a Chevy truck with a slipped harmonic balancer. I would advance the timing till it would ping under a light load, then back it off a few degrees. Ran it like that for 20 years.

Just wanted to say thanks to everyone. After installing the Stock Intake, Weber Conversion Kit and Holley Regulator my Jeep now runs good, vacuum is at 20 and my timing is dead on 9 degrees. I guess there must have been some sort of vacuum problem causing my timing to be way off. As you can see in the pics I didn't hook up the heater hoses going to the intake because Advanced Auto said they don't show any heater hoses going to the intake.

They're wrong, but you probably won't notice any issues throughout summer, but it could be an issue in winter. You don't have to have any preformed hoses there, just standard old heater hose will work.

Glad to see that you've got it all going.

They probably didn't show them because they're a discontinued part.. You've got to make something else work if you want them. There's a thread around here somewhere about it..

The heater hose that you have connected to the water neck should be connected to the rear of the intake manifold and then you should connect a 5/8" heat hose from the waterneck to the front of the manifold.

The weird thing about mine is the water neck is around 3/4" and the intake is 5/8". Hey Yarz thanks for the link.

I know it's tight. I bought 8 feet of 5/8" yesterday because the hose from the waterneck to the manifold is the one that I took with me to NAPA and was going to replace all of it. Turns out that the hose from the heater core back to the water pump needs to be bigger...didn't check the other connection from the core to the back of the manifold yet but I know that the5/8' will go on the manifold to water neck.
