I need some help on the valve adjustment thing.
Ok so I think I learned that theres 2 kinds of cams, a hydraulic camshaft and a solid camshaft (is that right?). I need to know which type came in the 69-79 350 blocks? because there's one where you tighten an extra 3/4 turn after zero lash and one where you get to zero lash but use a feeler gauge and loosen the nut. I need help please on which one i have

Either type of lifter can be used in any block. You'd have to know the original application, or what it was rebuild with.

so what your saying is that I can use a feeler gauge OR the 3/4 turn?

No, I'm saying you have to know what type of lifters the engine was built with.
