LSM is a top of the line company, Steve is a great guy to work with, very knowledgable. LSM really came into the limelight during the Pro Stock Truck heydays, they were pretty instrumental in a lot of development work and they have continued that. They are well known in the Super Stock, Comp Eliminator and Pro Stock ranks. We have run several 55mm and 60mm SS Hemi cams from LSM.
