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...

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...

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...

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

...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...

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…?

It's not going to be a night and day difference. Before doing anything, I would make sure the rest of the motor is up to snuff with everything working the way it should. Compression and leakdown test, optimize the timing and advance curves. If it's a high mile engine, you may need to open it...

I actually only need the threaded adjusters with lock nuts for a stock 1970-71 340. I've checked many places only with a NO, don't have: Bouchillon, Jegs, Summitt, Mancini, Hughes. This is a pic of the first two bent CompCam pushrods. The adjustable rocker arm set is for the 273 engine and...

When I talked to Mike at B3 a while back, he mentioned that the PRW stainless rockers have a nicer roller axle than the SM stainless rockers. They may be made in the same factory, but according to him, there is a difference in axles. He also recommended soaking them in oil prior to installation...

No one. Just Ma-MoPar did.

Hello Fellow FABOers, I’m fairly new to the big block scene. Can someone please tell me which adjustable rocker arms and shafts will fit inside a factory ‘68 383 valve cover? It doesn’t have to be roller tip. Is there a 273 style adjustable rocker arm made for the 383? Thank you!

First year up to a certain date, the oil holes in the rocker shafts weren't slot cut for better oiling. That can be and should be done. As mentioned, 2bbl and 4bbl used the same ones in a given year. '64-7 were solid cam with adjustable rockers. '68-9 were hydraulic cam with non-adjustable...
