Anyone know who makes these roller rockers ???

[BigBlueOvalFan]

As the title suggests, does anyone know what manufacturer's roller rockers these are and if they are worth holding on to ?  This is a mild all aluminum FE with a smaller solid roller cam and I noticed some AT Racing roller rocker sets for $175 for the set and thought I may swap those out and replace these if these would be better suited for a higher performance build that needs the strength of a higher quality rocker (if in fact these are higher quality or can handle a more aggressive camshaft/valve-train).  I also seem to think that I heard that some quality roller rocker sets have been discontinued and didn't know if these where the ones.  Any thoughts.

Thanks, Jim

Those look like Precision Oil Pumps parts, and they are way, way better than any $175 dollar ebay imported stuff garbage

The stands and rockers are identical physically to my Precision Oil Pumps items. They are rated for up to 700LB spring pressure and billet items.
The ones on Evilbay are often cast and have been noted to fail.  Just a thought.

Thanks guys.  What would you consider to be the best roller rockers on the market today ?

[67428GT500]

I see a lot of T&D here on the high output builds.  I am running the billet shafts, end stands, stands and spacers with the roller rockers but my cam profile are relatively mild compared to roller cam engines. 232-240@ 50  with a lift of about .570 and a spring seat pressure of 130 and 355 @ .600.
I think what you spend is relative to intended use and specification.

Thanks, I've also noticed T&D mentioned quite a bit but they seem to be in the $1,200 or more range.  I think I'm going to hold on to this set as they seem to be quality and can handle a more radical cam.  This current engine is a 527ci All Aluminum FE (Genesis Block) with a .645 lift solid roller cam 248/248@.050 and will be a seldom driven street car.  I found the following on eBay and think I may give them a try.  Any experience with these guys at AT Racing or this kit ?

Those look like a Chinese T&D rip off. Your cam and lift is pretty radical.  Hopefully, you don't have a rocker break. I've seen a few of those posted on the two FE forums.

I'll have to keep my fingers crossed.  They're worth a shot at that price, the car is gonna be a garage queen so I really don't want to spend $850 to $1,200 on a set of rockers.  I'll report back after I give them a couple rips when it get's back in the car.  Thanks for all your help.

You’re better off with factory stock rockers with good shafts. They can handle most street motors just fine. Besides there is a reason they are so cheap! You get what you pay for.

[67428GT500]

There's no way I'd run factory rockers and shaft on a cam like he is running.  Almost .700 lift and I am sure the spring pressure is well over 300 lbs.
I have seen a few sets here of Chinese rollers that were copies of the Dove broken in half where the shaft passed through the rocker.
Perhaps they will work well but the quality has been hit and miss.

Aluminum block, solid roller, and cheap "knock off" import rocker arms do not belong in the same sentence.
Nobody has ever heard of that supplier. 
Promise its simply yet another iteration of the Speedmaster/Pro-Comp garbage that 800 ebay vendors hang their own name on and sell.
It a "garage queen" - - it'll remain a garage queen with junk like that.

I've always been "a fan" of brand name parts.  My preference for rockers is Harland Sharp.  I have a set of Crane Gold units on the 302 that I bought in - ready - 1977.  The went in the motor in 1996.  I run Harland units on all my 351C engines and have no problems.  Plus, they are lifetime guaranteed.  Here's my eBay experience with sudo-named parts:  I bought a set of Jomar stud girdles for a good price.  The girdles were Jomar, for sure.  The nuts - not.  Bored off center, crummy threads and such.  The nuts were so bad I could not install the girdles.  The fix was to buy real Jomar nuts from Jomar.  And overall I saved - nuttin' .  Would have been time and $ ahead just to buy the Jomar kit up front. 

Trying to save a couple hundred $ on a really nice build is really unwise.  Buy the best parts and be done with it.  If I can't afford that particular part right now, the project waits until I can.  When I built the dragster, I spent $8K on the chassis and then spent another $11K gettting to the current state over two years.

The Blue rocker I think Barry is right. Mine were Ford power parts which precision oil pumps bought or however they worked that out. They are good rockers used them for 5 seasons on the street and every weekend for 5 years at the track, then car sat for 18 years without backing off shafts. Rebuilt motor and used them for about 2000 miles and broke a rocker and switched to Harland Sharps. I think that rocker could have been holding a valve open for 18 years who knows. Anyway I would buy them again.

They are made by Dove. Those aren't the old bushed FFP offering. Ron Miller hasn't sold a set of those since about 2001. The pushrod design in his posting tell us it's much more recent.

I inherited these blue rocker sets with a vehicle I purchased and they've been sitting (unloaded) on an engine for about 5 years.  I was fitting the pushrods for clearance on the intake and decided I'd lash the valves.  The picture is what happened when I hand tightened the lock nut on one of the adjusting screws.  Oddly enough, some of these lock nuts have "ARP" stamps and some do not so I have no idea what the unbranded hardware is (most likely original).  No reflection on the rocker set of course but I was a little shocked.  I'll be replacing all these adjusters with ARP hardware just to be safe. 

I'm not sure what brand this eBay rocker set is but here is the info from the listing;

"Our Procomp Electronics aluminum rocker arms are made from 6061-T6 or Series 7000 2024 aircraft quality aluminum alloy extrusions. Each rocker body is relieved for extra valve spring clearance and anodized for added strength. CNC machined billet steel pedestals, ground steel alloy rocker shafts, alloy steel fasteners, and needle roller bearings from the finest manufacturers in the world comprise the foundation of these rocker arm systems. These complete kits include all the components and hardware required for a professional installation.

Benefits/Characteristics

- Rated 750 lbs. open spring pressure
- Internal oiling system for long-lasting performance
- SAE 42100 full complement precision needle and cage roller bearings."

I'll have to double check my spring pressure as these heads were also inherited and POPS blueprinted the long block (which I plan to perform again just to have peace of mind).  But I think they are worth a shot and I don't mind being the guinea pig on the this one.  If they break, I'm out $300 and some time.  While I mostly agree with the comments that you get what you pay for, it's not always the case.  Sometimes you pay for quality and get anything but and sometimes you get a great deal.  I'll report back after it's run through some tests.
