How does the oiling of the pushrod ball stud work on the 273 rocker arms? I have inspected mine and don’t see any path that the oil can get through. There is a hole in the rocker arm yes. But the adjuster has some sort of interference fit with the adjuster screw. There is no channel relief in...

Hey everyone, I recently inherited this build from a family member and am slowly learning the world of pushrod engines. I am putting together this 340 with a hydraulic cam, X heads and which i believe to be a 273 or Rocker Arm Assembly. All seems to be going well but when i went to prime the...

I'm in the process of putting my brothers 273 engine together. I have one rocker arm that doesn't have a very good interference fit with the adjuster. I'm looking to purchase a replacement rocker arm with proper adjuster function.

I was surprised when I chkd specs on springs that the Lunati dbl 73949 has a smaller od(1.440) then comp 901(1.494). But I'm assuming the double doesn't need to be as wide due to dual springs? We never even thought to chk rocker arm clearance when we did the 273 in 2012 and it has the wider...

Mancini Racing - A Engine Adjustable Rocker Arm Set

I am very confident you will find the 273 adjustable rocker arm set you have for me. :poke::lol: If you find some I'm your man !

The closest you have is sending a set of the 273 iron adjustable rockers to Gary at Rocker Arm Specialties. He can manipulate the rocker shaft hole and make them 1.6. But as for stamped steel 1.6, no.

I've looked in five different factory and general service manuals spanning from 1957 (the LA273 shares a similar rocker arm as the A-block exhaust) to 1966 and cannot find any mention of or spec for rocker arm to shaft clearance. I have a pair of factory 1965 273 forged rocker arm assemblies...

I've been reading on here about guy's using 273 rocker arms. Are they a good choice for a budget rocker arm? Would they be a good choice since they are 50+ year's old? I can understand it if you already have them. But if a person doesn't have them what would be the next best choice for a rocker...

The pushrod looks like its rubbing the bore on the head?

I have a few new sets of small block Mopar rocker arm shafts for LA type cylinder heads. These shafts are made here in the U.S. from thick induction hardened steel. They feature banana groves and oiling holes that are positioned for the loading of mechanical rocker arms. These shafts have screw...

Is Gary on fabo maybe?

I have for sale a pair of what looks to be, OEM type 273 adjustable rocker arms. One is new and the other is used but in excellent shape. The adjuster end has been spot-faced so that a jam-nut can be used that will fit flat on the surface. I also have a new rocker arm that has not been...

A bit more on cast rockers. Jig up a couple of old 273 rockers and measure the lifts if you have time. Even the Mopar Perf. Iron Small Block rocker often varied .010 to .020 at 450 lift. Back then one of my sponsors let me go thru his whole stock of MP rockers to find 16 within .010 varience...

They measure cam lift at the rocker arm, I don't know how they can check the duration.

All right, first off you need to post some pics of your rockers. Stock '68 340s did not have adjustable rockers, so we need to know what you've actually got. At this point I'm going to guess stock '64-'67 273 mechanical rockers. You didn't say what the replacement cam is- hydraulic or solid...

...prepped versions in their catalog and recommended them in their build guides. And name one builder that hasn't used some form of 273 rocker arm on their builds. I'm sure the OP's use of the 273 crank was due to the smaller crank pocket needed to run the early 904. OP, I think your plug...

What I have is a Hughes Engine rocker shaft and shim kit with modified 273 rockers. The rocker arm shaft comes with aftermarket clamps thus the stock dimension between rockers is lost. Have installed shims as to maintain center on valve stem. Does anyone have any knowledge as to what the...

Ok. Fair enough. In some of your other threads though, this is the case. Sorry if I confused them. That said, are you going to question and argue with post #5? It shows so clearly a blind man could figure it out, yet you still question. The oil seeps through the threads. They are interference...

My factory 273 adjustable rocker arms and shafts that are on my 340 do not have the banana grooves on the shafts. They must be ‘64 assemblies…?
