This machine has been an ongoing project for 8 years as of this writing. It has an 8" lift, 35" BF Goodrich All-Terrain T/A KO tires, and the entire locomotive portion of the vehicle (from the engine to the wheels) is pretty much brand new.

After throwing thousands of dollars at it, I still have a driveline vibration problem at certain highway speeds. I've had a hard time convincing people that this is a problem. It is not in my imagination as it eventually loosens the U-joints on the rear drive shaft. Because of this, I hate taking it on the highway, which limits its usefulness.

If I ever manage to work up the desire to shell out some more cash, I may pay to have some experts put it on a dyno and attempt to locate the exact source of the problem. If the vibration were to go away, I would be one happy guy.

Things ruled out so far in the search for the vibration:

• Transmission - replaced
• Transfer case - replaced
• Drive shaft - replaced
• U-joints - replaced
• Differential - checked
• Angle of rear u-joint - altered with shims*

*Though I generally think of the people who did the shims as serious pros, I still believe this is the source of the problem. My readings on the subject seem to back up that theory. If you have any ideas, by all means let me know!

Edelbrock Performer 1400

Number of Barrels	4
Carburetor Flange	Square bore
Choke	Electric
Fuel	Gasoline
Secondary Type	Air valve
Fuel Inlet	Single
CFM	600
Throttle Linkage Type	Universal

Edelbrock's Performer carburetors feature two-piece, all-aluminum construction for cooler operating temperatures and less warping. There are no gaskets below the fuel bowl level for fewer leaks, and no plastic parts or power valves to blow out. The carbs use easily changed metering rods for precise tuning, and the primary venturi booster is a bottom-feed design for smoother acceleration and better drivability.

Purchased new through Summit. I am very happy with their service.

Edelbrock Performer intake manifolds are low-rise, dual-plane designs with patented runner tuning and a 180 degree firing order you won't find with the competition. This combination boosts torque over a wide rpm range, from idle to 5,500 rpm.

As with the carburetor, this was purchased new through Summit.
