| RE: Valve adjustment |

Gee Matt, I thought someone would have given you advice/instructions on this by now. I was too busy yesterday getting the very heavy T-85 mated up to my 427. All by myself with nothing but a floor jack and the '60 'liner up on jack stands. Had it just about there when John came by. Thanks John for that last little bit of help I needed for that input to slip into the disk.
Okay Matt, here you go:
You're right, you don't want to adjust FE 1.76 rockers like a small block Ford or Chevy. They'll be too tight as you found out. All you have to do is just take up all the slack in the pushrod and the rocker arm adjusting screw. This is kind of hard for me to explain this way so forgive me, I'll try to be clear and succinct.
As you tighten the rocker adjusting screw, make sure to keep the valve stem contact point in touch with the valve stem. Then just as you tighten to the point where there is adjusting screw contact with the pushrod - STOP! Push down on the rocker to make sure it's in full contact with the valve stem. Now check the contact between the adjusting screw and the pushrod. It should be in contact but not so there is a lot of drag when you twist/turn the pushrod. This is where the real difference is between a small block and an FE. There should just be contact so that you can't pull up the push rod indicating any slack. Now, just set your ratchet handle at high noon, and give it a 3/4 turn to like 9:00. As I think about it, since you've started the engine, you have the hydraulic lifters pumped/filled, cut that turn back to just 1/2 - 6:00. That should do it. If you are getting some lifter noise, try to pinpoint which one is ticking, and give that one just a little for turn at that adjusting screw. Just a little bit. A little is better than too much.
I hope this makes sense to you. With even a mild to warm performance cam, I personally like using the adjustable rockers. They offer a tad more lift with the 1.76 ratio over the non adjust. 1.73. Good luck. After all the ticking is gone. Install good valve cover gaskets for one last time. Then forget about 'em and enjoy driving. |
