Off What engine, 273 solid lifter??

No much of a BB guy. But I know mopar made some cast rockers for some apps. My friend had them on his 413 '62 300. But I can't say they came stock on that particular app. Maybe on the early HP 383's, or RB Stage cars, or some long ram 300 letter cars. I think Isky made some, too.

Looks like I will have my work cut out for me. Never easy but I will get it done right and not have to worry about it again. Thanks for the info guys.

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.. They are made from thick induction hardened steel. They feature banana groves and oiling holes that are positioned for the loading of mechanical rocker arms. These...

Small block 1.5 rocker arm assemblies. As far as I can tell, these are the older style Comp "magnum" rocker arms (#1420) that aren't produced anymore. They are not bushed, and from my research, are chromemoly and are not recommended for open vale spring pressures over 350lbs. Please note that...

Putting together my solid lifter 273, all stock parts. I have the shafts mounted with the oil holes pointing down towards the exhaust ports in the head and each shaft hole lines up with each rocker. These are cast, not stamped rockers, and I can't find assembly info in the service manual. This...

Next time you pull them off to have a look see, take a look at the bottom side of the shaft, and particularly at the bolt hole in the shaft where the oil comes up from the cam thru the head to oil the rockers, and see if that hole is larger than the other hold down bolt holes in the shaft. I dug...

I need a couple 273 rocker arm adjusters. Thanks

Thank you for that, And yes the oil holes in the factory 273 shafts are larger then the others. They are installed correctly , Notch down facing inward. Or like you said looking at whichever side of the engine your putting them on, notch down to your left. I'll check the PRW Shafts I believe...

Your comments about clearance in relationship to shaft diameter are partially why I posted, and, to be clear from my end understanding you weren't responding to me, I understood your suggestion of chroming to tighten the tolerance. The rocker shaft is a similar diameter as a piston wrist pin...

On post #109 is a picture of this 273 with the very heads and rocker arm system used during the dyno runs. Is 426ci 360 a small block? As noted in the thread, later the heads were used on a stroker engine with bigger valves and further modifications.

Spring pressures and cam lift shove that rocker arm up n the springs resistance is shoving it back 'hence the wear position/witness marks'...those bushings imo have a tendency to wear in & leak out the top. The bushing material matters too of course. I too have a nice set of 273 rockers they're...

I am in the process of finding the proper push rod length for my SB with 273 rockers and a hydraliclic cam. My question how far the stock adjuster need to protrude from the bottom of the rocker arm. Thanks

typed that wrong....I mean I measured using a couple of adjustable pushrods meant for measuring the proper length to use from lifter cup to rocker socket for the non adjustable rockers and I also used the measuring pushrod for proper length cup and ball type pushrods needed for 273 type...

This should be the case for most heads used on the street and light strip applications. The quoted words are aimed at a specific head for a specific use. He’s not wrong, but remember you can’t effectively make good usable power with a tunnel ram, twin 950’s, 2 inch tube headers, etc…. On a...

You might want to contact Hughes Engines about torque for the head bolts and rocker arm fasteners. We were giving values for stock fasteners. Stock rocker shaft bolts are only grade 5 standard bolts. I only asked about the torque plate as fastener (head bolt) torque has an effect. No worries...

I haven't looked lately, who makes a good 1.5 ratio rocker arm that's not a roller tip, something like the 273 rocker arms?

You assume a lot. My dislike of hydraulic lifters of any kind, Rhoads or otherwise, comes from the fact that they are an inaccurate way to actuate valves. Most hydraulic lifters have a plunger range of about .100" or so. Some more. As a result, you never know how much those plungers are moving...

Valve covers have been off. 273 adj rockers. valve springs, pushrods, shafts, etc all good.

Just to close the loop (and gloat a little), I picked up the Sioux Valve and Seat grinder setup I found on CL locally. It is in excellent mechanical condition. The seller said the original owner disassembled and cleaned it after every job and after he got it, it was used in 1992 for rebuilding...

Here are the replacement studs and nuts that we used for the 273 rocker arms in this thread: Crane Cams 99802-16 Crane Shaft-Type Rocker Arm Adjusting Screws | Summit Racing

"Looks like"... It leads back to like Rusty rat rod was saying everything needs to be checked. We look at these pictures on the internet and try and diagnose from that when it's op who needs to do the leg work. I always make sure I can slip piece of rounded welding wire behind the spring and a...

I need a single 273 rocker arm with a good adjusting screw. Thanks

...fix them. I have a couple that the new adjusters loosen up a bit but not enough to cause any issues. They quiet down when it get's warmed up good. Now, a lot of these are sales and wanted threads but just scroll on by those. Search Results for Query: 273 rocker arm | For A Bodies Only Mopar Forum

yes you can use the 273/318 ones (assuming the 273 is a hyd lifter cam). no opinion if new is needed. on mockup check the lifter preload to find out if you need different pushrods & go from there. I wouldn't think you would need custom lengths but if so watch the straub industries utube vid on...

Looking for a single rocker arm from a 273. It appears my set has 1 odd ball! Looking for one in excellent condition with the adjuster screw/ball in tact. Rocker has the number "380" on one side of the arm. Thank-You.
