Nice power!

Installed this as part of a rebuild. The .520 cam combined with the Super Stock Heads and 3 1/2” domed pistons, HL2T lifters, standard forged rocker arms and gearless reed valve crankcase breather and Super E carburetor unleashed unbelievable power in my wife’s ‘98 Electra Glide! It’s a nice strong and quiet build with a cam that pulls hard at 1000-3500RPM and has a nice THUMP! On the next build, I will try the .561 cam for someone who likes to really get into the throttle!

I would recommend this product
