Actually, I like the looks of their balancers that fit on the driveshafts. I've dealt with similar items before such as fluid filled harmonic balancers. Had a 402 that we just couldn't get a vibration out of even after the installation of the fluid filled harmonic balancer. In the end, just threw a whole new motor in the truck and set the other motor off to the side.
As far as Amsoil. I'm a firm believer in the stuff, but I don't consider it the end all product. Some people are members of the Amsoil cult. Therefor, it could be a religion, therefor I guess we should not discuss it any further beyond my post. Sorry Jedi.
