With the new drivetrain, the Galaxie has been sitting too long without having any work done on it so I'm slightly bored and am wanting to do a little wrenching. I was thinking that with the new build, my cam may be a little too much for the stock rocker assembly. I've pondered purchasing the end stand supports from Precision Oil Pump but would like to know if this would be a wise choice given the following cam specs: Elgin hydraulic cam = valve lift 536 int./562 ex.-duration at .050-224 int./ 234 ex.

I also noticed they went up in price quite a bit since I last looked, so if anyone has some they're looking to sell, I would be interested.

After thousands of miles and 3 different engines, this jumbo shaft gave up with a Comp 282S and matching springs. Now I'm back to regular duty shafts and end stands. Set and forget.

It eliminates a known weak part of the FE. You hear the guys say I ran this and I ran that without them. Then talk to someone who did have a shaft break (me) and you sure wish you would have had them. ww

I'll purchase them soon. I was certain doing so would only be beneficial given the possible disasterous outcomes of running without. I just needed that extra push to spend $120. Guess I'll live on ramen noodles for a while.
Thanks for the comments ya'lll.

I have a new set of POP end stands I'm not going to use. e-mail me

Pardon my ignorance but what does an end stand do?

Thanks in advance

the end supports go around the end rocker arms and provide support for the other wise unsupported far end of the rocker shaft.

The rocker shafts are held in place with 4 bolts thru stands. The the ends of the shafts are not supported, they are kinda cantalevered off the stand. As you increast cam lift and valve spring pressure the shaft flexes and breaks. An end stand is a device that cradeled the rocker arm on each end of the shaft and helps stabalize the shaft. Here is a picture of the end stands. This setup uses the complete Precision Oil Pump rocker arm shaft support system including the end stands, the center stands and spacers. ww

slot to better crimp on the shafts (rare), the Prescision Pumps style stands of alum with a slot and fianally the Dove style alum stands that utilize all four corner head bolts with stud tops to further support the ends of the rocker shafts. I personally found a bracket racer that ran a stout .600+ roller cam with the factory iron stands that pinch on the shaft, he did break an occainsional rocker shaft end, but obviously broke a hell of a lot more factory and aftermarket factory like adj rockers.
The fact is the shafts always break at the hole for the rocker stand, in the past there wers robust extra-duty shafts sold, some even with small dia allen screw plugs in the ends. I note Precision Pumps mentions their slotted stands pinch down on the shafts. If you think about it if the stands were made of tool hardened precisely fitting steel that would add a bunch of supporting strength to the shafts compared to alum, that you know flexes like hell.

in the stands but then Ford Engineers were a lot smarter than me. If the shaft is a fairly snug fit through the stand it isn't going anywhere so why weaken the stand by cutting one side out? As for end stands, I never broke a shaft without them but many have so why not at the price. Just looking at the stock setup tells you it's a problem area waiting to happen as soon as you add spring pressure.

The problem with the stock Stands is that as you torque the Bolt down, it 'EGG SHAPES' the hole in the Stand. The Stand then supports only the top and bottom of the Shaft, not the sides. Obviously, with no support on the end position of the Rocker Shaft, this area becomes the weakest part of the Assembly, and as cyclic use occurs, failure ultimately follows. This is exacerbated by increasing spring pressure beyond 290-300 pounds with Stock assemblies.

When you put a 'Slit' in the Stands, torqing the Bolt pulls the ends of the 'Slit' together, leaving a more or less circle to clamp on the Shaft and support it in 360 degrees.

The Egg Shaping should be apparant to anyone who has ever tried to take a set of stock Hydraulic Rockers apart, as most of the Stands need to be beat off the Shaft with a Rubber hammer or some other means.

That is why Ford put Slits in the Stands. That is why most guys that manufacture them now also put them in(like DSC).

Hope that sheds some lite. ANYONE using Adjustable Rockers in a HP setting should consider either putting slits in the their stock stands, switching to aftermarket Aluminum or Steel Stands w/ Slits in them, using a Premium Duty Rocker Shaft or using End stands. These items are commonly available thru most of the vendors listed at the top right on the Forum Vendor listings. DSC is one of them.

I have had to beat the stock aluminum ones without slits off the shafts but would think a quality stand would not distort the hole at the low torque value one puts on the stand bolts. The shaft stresses the stand top and bottom and much less on the sides so in my mind the slit still serves no useful purpose and actually weakens the stand. I'm sure it wouldn't take much to prove me wrong but if I had my way, my Erson stands wouldn't have the slits.

Dale, my Erson roller rockers are very early production versions (black rockers, snap rings at the ends of shafts etc), and they do not have any slits in the stands. My Ersons have been trouble free since I first bought them years ago.
