Review on ๐Ÿ”ง Spectre Performance 4699 Harmonic Balancer Bolt: Enhanced Engine Efficiency and Stability by Gary Haymon

Revainrating 3 out of 5

The bolts are not long enough for use with the secondary crank pulley

The bolt was too short in thread depth and length. If you're using the stock crank pulley, you'll need a longer bolt, about 1/2 longer than the class 8 bolt, which is thick enough for washing machines and pressure washers. Bought for my 68C10 SBC 350
