    Rated 3 out of 5 by from Nothing Special Weights and cam are 'cookie cutter' copies of every other aftermarket advance kit out there. Springs are the only part that varies a little. Instructions are pretty poor, there are a couple of non-flanged bushings in the kit and it isn't evident at all how or where they are used.

    Rated 3 out of 5 by from 40004 - JEGS HEI Advance Curve Kit I bought it last month. Other than the bushing not fitting because they were too small. I had to use the old ones. I but it is working fine.

    Rated 2 out of 5 by from Bushings don’t fit JEGS distributor The bushings in this kit don’t fit the JEGS brand distributor I ordered, and the weight hole sizes are also too big for the pins on the distributor. So pretty much only the springs in this kit are worth using.
