273 adjustable rockers need refurbish.
I had done a search on here looking for 273 adj rocker mods/info and it led me here. Sometimes I would rather read an old thread rather than start an entire new one.
Informative thread,adj rockers can be used in any combination(hyd vs solid in both pushrods and lifters), didnt know that.
Can I spot face the rocker top with a belt sander? Suggestions?
Hope the OP is getting things ironed out??
I wish. Money being the biggest obstacle. Still haven't got the rocker arms mounted and adjusted yet.
I have the rockers honed and cleaned up. Needed to grind some material out to provide clearance for the valve spring. That is done, (finally) ordered pushrods last week from Smith brothers, nice work. They ended up being 7.0625 working length.
Ordered banana groove shafts from Hughes. Then I noticed today that there isn't a set of holes for the cup and ball oiling hole. Called Hughes and he said the shafts they make are not designed for the 273 adj rocker. They are designed for the Rocker arms he sells. He's taking them back for refund. I have to say that is good customer service,can't complain.
I have a new set of hyd stock rocker shafts that I will drill to provide oil to the cup and ball. The oil hole on the hyd shaft has a significantly larger oiling hole, approx .177, the Hughes is .125.
Any suggestions on hole size for the cup and ball oil hole?
Also, location for that oiling hole?
Should I put a small groove in the main hole?
I do appreciate the input from the membership here, a lot!
That's tomorrow's project.[/QUOTE]
