Stock rocker install

[Sonny]

Can someone point me to the assembly and installation basics for stock 440 rockers and shafts?
Thanks

You should be able to find it here somewhere. Good Luck

Rights and lefts...

Make sure the oil holes in the shafts are pointed down and toward the valves.

Torque shaft bolts to 25 ft lbs. No more than that or you'll smash the shaft.

Trying to find you a good picture.

This pic shows how they're assembled. Notice the long and short bolts, also the narrow and wide hold downs.

And as you tighten the bolts down evenly, continually verify the pushrod tips are in the rocker sockets.

if it helps....

I’m about to do this too. Here is a good picture of them up close. The 314 should be a right and the 262 is a left if I read the above post right

On a side note, anyone recognize the numbers on these as to what brand they might be?? They are near new, but I got em used in a parts swap deal...

And one more trick... When installing the rockers the pushrods want to move every which way.... A straight piece of welding rod/coat hanger wire/bailing wire laid along the inboard side of the rocker pedestals keeps them from falling outward which is the direction they most try to fall... And the hardest direction to retrieve them from...

Those are factory Chrysler rocker arms

I have seen those numbers all over the place and not consistent honestly

Right and left are easy to tell based on the offset push rod socket stated in that picture 6-55

69-71 Factory Parts manual shows the same part #s L/R for all 383/440 rockers

However , supposedly starting on the 69.5 A12 Sixpack the rocker arms where stamped heavier gauge steel from the factory

Around .140” Thick

Mopar Performance used to sell the heavier gauge steel along with Mancini Racing , but no more


I run Sealed Power stamped steel rocker arms and shafts on my 383/432 Stroker with E Street Heads

The measured thickness on the new Sealed Power Rockers was slightly thicker and looked more consistent then my factory original 1971 383 rockers

Sealed Power .140”/.145” Thick when I measured

Stay away from the Elgin Industries stamped rockers if buying new , I returned two sets before I found the Sealed Power parts made in the USA , night and day difference seriously

I’ll measure the thickness now, out of curiosity. Now, where to measure?

Push rod socket area

Read this from Chrysler back in da day

Thanks for the tip on Sealed Power Rocker Arms
Any source for the thicker ones today- I have not seen any in years except NOS
All modern lifters are the 2011 AMC type so oiling the cups through the pushrods is a no extra cost option - really helps on the pushrod and rocker ball galling > push through issue
I have mentioned before that putting a higher lift cam under used rockers and pushrods is a disaster waiting to happen.
The ball socket are worn in and there is a ridge at the wear point which then has to be ridden over with the additional angle. Way lots of new pressure

FWIW or reference......
a new left and right MP socket thickness section measures .114" (that's one hundred fourteen)
