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...

I recently purchased some Mancini 1.5 roller rockers for my bracket car, link below. Mancini Racing Aluminum Roller Rocker Arm Kit The motor in my bracket car currently has 273 adjustable iron rockers on it which ran fine last year but I wanted to upgrade. Is it reasonable to believe that I...

Need some help. I've purchased a CompCam hydraulic (High Energy) cam and lifter package for my 67 Dart 273 (252/252 duration, .425 lift). My question is: With the engine originally having solid lifters I'm thinking I need to replace the adjustable rocker arm assembly as well. Can I use the...

Think about this. When the W2 heads were released they used ductil iron rockers, not unlike the 273 rocker. Both are pretty much indestructible barring severe abuse.

Thanks for this chart, again thanks for your help. Glenn

FE ford engines 390,428, 360 ect always needed rocker arms and shafts if you slid the arm over on the shaft and inspected it they used springs for spacers they are set up just like mopar 273 but not adjustable and no groves on shafts they were always wore out /with hydraulic lifters

Looking for a set of 273 rocker arm shafts for adjustable rockers with the grooves in them. Must be in decent shape. Message me if you have a set you’d like to sell.

The last year for the 273 was 69... 67 was the last year for the solid cam/adjustable rocker arm 273's... 68 & 69 273's had the same hydraulic camshaft and rocker arms as the 318 for those years... Refer to the charts in this article: Factory V-8 Engine and Cam Specs by Year 1965-1975

Whe I click Amazon link I get "currently unavailable " must be cuz I'm in Canada? I see nothing that gives thread size?

The Chrysler rocker arm on the 273 and the 70 340, 6 pack do not have a lock nut they have a varying thread that causes the tension between the adjuster and the rocker arm that holds the adjuster in place when you adjust it. Now the thing that you do is you tap those rocker arms out to...

You want to make sure the thread size matches the factory rockers. For whatever reason ones to fit stock rockers (but tapped) are hard to find.

OEM 340 6-pak engines did have the machined pad and jam/lock-nut on the adjuster. Got a few questions: * Does the OP have hydraulic lifters? (273 pushrods are normally about .25"-.30" too long for hydraulic lifters.) * Were the rockers shimmed because the pushrods were too long? *...

And..."The 1965 high-performance Commando 273-cu.in. V-8 four-barrel engine had a chrome air cleaner and cast-aluminum rocker arm covers with fins.." well, half right.

I am changing cams in my 67 273. Swapped out the solid cam and installed a flat hyd. I added small dual springs and guess what. Some of my adj rockers rub the springs. Now I'm sure some of you are giggling by now as I have seen these posts before. Question. Do I grind these rockers for...
