valve adjustment help
I just finished rebuilding my 289 and have a question on how you guys adjust the valves. When I adjust the valves I tighten them until the pushrod still can spin.
Thanks in advance

I assume you have adjustable rockers since you are asking this question? After putting the cam on the base circle, I tighten until all slack is removed (pushrod will still spin easily), then preload lifter another 1/2 turn for a street motor, 1/4 with rowdier cam profiles that frequently see higher rpms.
Attached are instructions from Ed Curtis of Flowtech Induction. He is a very respected custom cam guy. Not as simple as some instructions you may find, but this method gets you on the base circle everytime.
