Hi!

I was wondering if I have wrong kind of rocker arms in other side of my engine. They have offset in pushrod side end, and allso in the valve side end, but both offsets in different direction. I think they are allso a little bit too long. Am i having a big block rocker arms here or am i doing something wrong?
But don't get me wrong. I did notice there is left and right handed rockers in both of these. :)
Just sold my other rockers to a friend cos i tought that i have these.. But i didnt check these first. #-o
 
Not so good pics, but maybe you get the point, and see how the rocker arm meets the valve. If I swich rocker places, push rods will touch the heads.

It looks to me that some of the rockers are out of order on the shaft. They are not big block rockers.
 
That rocker should be to the left of hold down bolt & the one next to it should be to the right of the hold down bolt. They are in the wrong order.

Thanks, but i think i tried that. If i remember right, it made push rods slanting and toutching the push rod hole in cylinderhead. I allready have some bent push rods in trash can. I don't need more of them. :D
 
The rocker tips are quite wide, they don't need to be perfectly centered. Also the slight offset causes the valve to rotate, extending it's life.
 
You've got them on the shaft backwards I think... Correct rockers, wrong execution.
 
I'm 100% sure that 8 of my rockers are something that my 318 didn't originally have.

First pic showing the ones in the passenger side. Length: 76mm (2.99inch)
They fit well, and pushrods seems to go trough the center of the hole.
"93RT" or "93LT" stamped on them.

Second pic showing the drivers side. Length:84mm (3.3inch)
Just "T" stamped on them. I switched few as i was told to, but now the push rods are touching the head.

So what are these?

I think you're correct... They must have swelled... :D I have some for free if you need them.

Yeah, they have grown up. Maybe I just disassemble my 318, and put it in the same box where I found these rockers, and feed and wet it regularly. Maybe it will grow up to a 440. :-D

I would like a free rockers. :D If you decide to take a little swimming trip, send me a PM. Only few thousand miles... :-D

Sorry, this is getting a bit off topic... To be honest, i think it would be cheaper to by some rockers from Finland than send free rockers over seas.

But hey, someone has been driving with these rockers! I bought a pair of 4027593 heads, and these came with them. I noticed that these heads have bigger holes for pushrods, comparing to the heads im using now. Only 10 pushrods came with, and one of them has bent, and one of them has scratches... I consider that as a proof that someone has used these rockes in small block.
 
To identify right and left rocker arms look at the pushrod socket.
The left rocker arms socket is left of center, and the right is right from center.
On the right side of your engine the rockers even say LT=left\\RT=right.

Install the rockers on the left side of the engine the same way.

Get your self a new set of hold down bolts for your shafts.
You should not be using off the self bolts and washers for rocker shaft hold down bolts.

Get your self this book>>>> how to build small block mopar engines by larry shepard.
Basic information plus good performance info.

Everyone who owns a small block mopar engine should have a copy.

Whats with the washers on the rocker shaft hold down bolt on the left side of the engine????
You should not have to use those.
It looks like they could hit the rocker when running.
Good luck.8)

Been there, replace hold down bolts with grade 8.

Looking at these picks of the rockers, I have a similar question. I have a 66 Barracuda with 273. I have a hydraulic cam and lifters and had adjustable rockers, originals I think. And they had spacers between the rockers. I replaced the adjustables with Hydraulic rockers like the ones shown in FinD pics. When I installed them I did not use any spacers as I read on mopardiy.com that they do not require the spacers. And in looking at the photos in this thread, I don't see any either? So can someone give the low down on whether or not they do or don't need spacers?
Thank you guys .. All of ya'll

no spacers
 
Look at the 1st pix in post #10. See the curved flat metal pieces under the rocker shaft bolts, that curve around the shafts? Those are the spacers and go between rocker pairs as shown. There are 5 of these on each side, 3 narrow and 2 wide. The 3 narrow ones go in the middle and at each end.

These are not like the ring spacers in the adjustable setups. The rocker pairs have no spacer between them like shown.

The pushrods are different like you probably already know.

There are square notches on one end of each shaft; these go down and to the left as you face each side of the engine.

BTW, the bolt torque needs to be 15-18 ft lbs; many service manuals list it higher which will result in broken bolts.
