a Hyd grind is fine for this endeavor. This is why I got it for the wife’s ride. Her ‘67 Cuda is a similar build and she wanted the ability to drive it everyday without a big cam but make good street power.
The 1.6 rockers add a minor duration bump and the added lift makes it a little more intense. The car clearly pulled past the listed rpm range to approximately 6100/6200 rpm. By then, we were really picking up the mph. The drum brakes are not up to par for these speeds. LOL!!! (~SCAAAAARRYYYYYY~)
