The hyd flat tappet cam works great and offers the simplicity, reliability and low cost of stamped steel rocker arms. The solid will make more power but will require the added cost of adj rocker arms with additional high quality adjusters, the correct push rods and the occasional lash adustments. I suggest for a super hot street driver to stick with the hyd flat tappet cam with good stamped arms.


Keep old mopars alive.
