Hi, all. This is my first post and want to say hi to everyone. Bought a Unique Cobra a month or so ago (#4279477) and have spent most of the time getting the bugs out of it (even though the previous owner said it was "perfect"). It has a Southern Automotive 406 in it and seems to run OK after I re-jetted it. I'm at 5500 feet just outside of Reno and the car came from Georga, near sea level. I do, though, need some advise. I've had all four wheels balanced (they were all off a little with one being way off) but I still have a front end shimmy at between 55 and 60 mph . Could it be alignment and not just balance? Any experience in this area would be appreciated. I'll attach photos when I learn how to do it.
