Hi guys. I'm attempting to adjust the valve lash on my 1966 427(390 hp) with 1969 heads. I don't know what cam it has. I don't even know if it is a solid or hydraulic lifter engine. What can I do?:confused:

If the lifters don't compress or when the cam is in its base there's a gap between the rocker and valve you should have a sold. Solid will typically have some ticking more so when needing an adjust.
