I believe some old school regrinders grind a quick hydraulic lobe on the solid lifter cams because they can get more lift if they eliminate the valve lash. Chris Neilsen and Schneider are two of the traditional Poly cam regrinders, but I like the choice of grinds at Bullet, and the cost is reasonable, too. Camshafts and intake manifolds are the two bugaboos waiting for you in Poly-land. R.

Back in the day, before there were many 318 higher compression pistons available, this was a favorite trick. R.
