Hi All,
I've finally got my 41 chevy sedan on the road. Overall everything is running well.
It has a Chassis Engineering Mustant II front end.
T5, Nova rear end (2.73), 28" rear tire, 2000 rpm @ 70 mph.
New tires,balanced.
Alignment done.
The alignment guy was able to tell with his equipment that the font end and rear end were in straight.

Here's the issue, I have a bizzare vibration in the front end.
It starts to happen as I approach 60 mph, and pretty much stays there after that. There is not a specific mph that it happens. It seems to have a mind of its own. Here is the bizzare part, it's NOT a constant vibration, it happens in a wave. Vibration... smooth.... vibration.... smooth... vibration... smooth (you get the idea). In the front end, I feel it 100% in in the steering shaft (the front end does NOT shake), then move through the body from front to back (mildly).
Here comes the wave... steering shaft... rear windows rattle (very mildy).... rear end (barely noticeable, may just be my imagination). .. starts over in the front.... All in perfect time, just like a wave of motion moving through the car from front to back.

The vibration isn't severe.
I have had three different sets of tires and wheels on the front, all balanced, and it happened with all of them (I was actully trying different sizes in the front for appearance/fitment, it had nothing to do with the vibration).

It's not so bad that I don't drive the car.
The faster I go (over 60) the faster the vibration and the wave, but the actual intensity does NOT increase.
Acceleration/decelleration doesn't seem to effect it.
Going straight or around a curve doesn't seem to matter.
Really bizzare.

Thanks.
Joe
