SCORPION ROLLER ROCKERS?

I'm looking to buy a set of new roller rockers, and I was looking at Scorpions based on price. Can anybody tell me if they're a good deal as compared to Harland Sharp, or Crane? Are they sturdy enough for a mild 521 build with a "street mechanical roller" with a lift not exceeding the low .700 range? Also, where are they made?

Wayne

Made in the USA and strong enough for your application.

I have these on a 532 solid roller deal

I ran them on my 470 pulling truck motor where every pass we buzzed it 8200-9000. After 4 years, I had to replace 3 of them as the bearings were not rolling freely. They impressed me enough that I bought a set for my new drag truck project with a 514.

I've run them for years. Great product and great warranty.

Thanks for your replies, my order is placed.

Life time warranty last I heard. Got mine new from a guy that got them replaced no charge.

Check those in your PM box.

I am!

I've just bought a set that I'm getting ready to install.

Wow they went to war on that set. I guess $260 to the door is not to bad on a $300 plus set of rockers.

Check his other stuff out he has 427FE parts and a bunch of old Ford gooodies.

They are manufactured in Florida.  In my opinion, they are entry level cheapo stud rocker arms that are competitively priced relative to their overall design.  I have used them on flat tappet applications but don't use them on big solid roller valve trains for a number of reasons.

If I were forced to choose between the three brands you noted in your original post, I'd opt for the Crane rockers.  That being said, the ideal rocker arm(s) cannot be selected without knowing more details of the build.  But ya, the scorps will open and close the valves....

Not gonna argue with you Paul. I know you have built way more engines than I have. I can only post my experience with them. Don't get me wrong, I would have loved to have installed Jesel's but decided to put the money elsewhere. Below I posted a link to my Youtube channel, and you can see that we buzzed the motor, and the scorpions handled the job nicely. I ran an .800 lift cam with Manley nex tech triple springs.

No-one in this thread is comparing Scorpion to Jesel shaft rocker arms.

The original inquiry was for opinions between Crane, H-S, and Scorpion stud rocker arms. The OP simply asked which brand each of us might opt for, and between the three stud rocker arm options presented and based on the limited engine combo info my recommendation is for the Crane rockers.  If you opt for the scorps then present your choice to him, not me--you already know how I feel about them.

Incidentally, it seems the purpose of your video is to show me a roller cammed, high rpm engine that is running successfully with Scorpion rocker arms. For the record, what I see is an explosive device where the rocker arms are the fuse. But don't worry, Alan, should the engine self destruct as a result of a failed rocker arm Scorpion has a lifetime warranty and will replace your grenaded engine with a brand new rocker arm...and it will be identical in design and materials to the one that broke all on its own in the first place.

Yes, the OP asked about Crane, H-S and Scorpion. I was just stating that I really wanted Jesel's but settled for Scorpions due to budget concerns but was happy with them overall. As for the Explosive device. Yea, they all are when buzzing that sort of RPM.. My rear puckered everytime, but not because of my choice of rockers. The vid link was simply to show that I successfully ran Scorps for several years in a High rpm motor. It sounds like I had better luck with them then you have had.

To the OP, I apologize, I had no intentions of derailing this thread.

No apologies are needed, I enjoy the banter back, and forth whether it's negative , or positive! I wasn't sure if the the Scorpions were off shore, or American made - and now I know. For my application which will be a "sunny day cruiser", that just might see the drag strip once just to see how she will do, I think the Scorpions will do the job. If I was driving that pulling rig, my butt hole would pucker too, regardless what rockers I was running (LOL). Thank you everybody for your pro's, and con's - much appreciated!

Cool vids...you guys sure work those motors hard.

As for scorpion rockers, I've had them on multiple builds with no issues. Most recently we put them on an ~800hp 557 that will spin over 7000 rpm. Frankly, I'm more concerned with the factory (4-bolt conversion) D0VE-A block than the rocker arms.
