Any reason you are choosing Edelbrock over UMI? Just curious.. I will be glad to help!

This item kind of goes back to the old saying "you get what you pay for". Edelbrock makes great products... however there F-Body torque arm is merely a factory replacement only and under hard load we have seen many of them break. If you do a search you will see what I mean. Now if you just looking for a stock replacement it would be just fine. But if you plan on any racing I suggest giving us a shot.
Pinion angle can cause vibrations if set to severely... however our torque arm is set in a good location that will not cause this.
If you would be interested in our product shoot me a PM and I will be glad to help
