put the cam lobe on the valve that you are adjusting on the base circle of the cam and a and use a feeler gauge to set the valve lash . i like to adjust the valves with the motor at operating temp and i adjust them to 0.25 . mike
Steve, I like to use this procedure. It lets you adjust 4 valves at a time. Adjust the pushrod so that it is obviously loose(you can move it up and down). Then eliminate the clearance to 0 lash, then 1/4-1/2 turn more, and you are done.
If, when adjusting them, you slowly lengthen the pushrod just until the wiggle is out and then go another 1/3 or so turn, you'll have the proper lash for a 455. I run these and that's what I did and have had no problems. Just don't overtighten the nuts when locking them down. You can break them. Ask me, I did it. I do have some extras if you should do the same. Just PM me. Phil
Thanks guys for the info....but got another problem homonic balancer came loose ,through all the belts hope this can be repaired since it didnt seperate from the crank.
Did the outer ring fly off the center section, or did the balancer bolt loosen? TA Performance makes a nice reproduction balancer. Any other damage done?
balancer bolt was missing the large washer,guy that build my motor left it off .replaced the washer everthing seems ok.Should have everthing back together tomorrow,will let you if everthings ok
