273 rocker info please
My last post on this thread
The best factory equipped standard mopar LA adjustable rockers I have seen as far as quality is 1967 273 and 318 LA engines "Yes 318".
I never had a set off a 66 LA that was original. I never stripped one so I have no info on them. But the 64 1/2 -65 to me looked weaker do to being thin. This is just my opinion from what I have seen over the years machining them. Also some of the banana groove shafts only have one oil hole. Some have two. We always drill the second hole.
My rockers are all at the new shop or I would get the numbers off the sets that I feel are better to use.
You can visually see the difference in these two neither were machined yet. You can see you will not get a nut on the one to the left without cutting it. The taper comes right to the edge of the hole for the adjuster. Also look at the width of the threaded boss and the oil hole for the ball. I took these pictures years ago to send to my son.
