Scorpion Roller Rockers

Has anyone had any experiance with Scorpion Roller Rockers? I need a Roller Rocker for a SBC to clear 1.550 Roller springs, my current RR wont clear, I have 1.540 Roller springs on a set of 220CC PTL aluminum heads, the springs im using are part #3600 (PBM) I also have 7/16 rockers studs as well, I believe the Rocker suggested for these heads with these springs is the scorpion #1001. Is there an alternative RR than will clear these springs thats affordable? I have checked the price of the scorpion RR and the price is very attractive...

any info will be very helpful...


thanks, 2wld4u

The Scorpions look to be a rugged rocker arm. Wish I had an answer for your clearance question.

Unless someone here knows for sure....I'm guessing a call to Scorpion is in order. May as well get it straight from the source.

They should change the name from Scorpion to "You Get What You Pay For" rockers. They could come in 1.49:1, and 1.58:1 ratios. Just like in that one movie where they tell the truth to sell things.

rockers

Roller rockers and 1.550 springs have been a problem since the dawn of time. I can't hardly believe that the people that make them don't look into the proper fitment closer.

Well anyway i put a set of scorpion ( very reluctantly) on a 358 late model engine. They ran the engine for a whole season with out a failure. When i got the motor back for tear down they looked really good. The spring pressure was 140 seat and 360 over the nose. They are back on the spare motor now.... That was 2 years ago and i can't remember for sure but i think they had plenty of room at the springs. I would call scorpion and double check though as someone else suggested....

Absolutely nothing wrong with Scorpion (Made in USA) rockers. I've been running them on my stroker for a year with no problem.

If you want to spend more than $200 for a set of roller rockers have at it, but I've never heard anything bad about the Scorpions. If someone is having failures, I'd look to the application and valve train geometry before I put blame on the "product".

Ed Curtis at www.flowtechinduction.com sells them. If they were "crap" he wouldn't have them on the shelf.

Yeah, I already made contact with ED, the rockers I need is out of stock at the moment, he also said that it could be awhile because of the weather in Florida at the the present time, he did however give me an alternate rocker to use and that is the Comp Cams Pro Magnum Rockers, @ 265.00 though I may just find someone who has the rockers I want in stock...

and to shed some light on Scorpion Rockers, several Pure Street Racers have said that they are using them with great results so Im assuming they arent junk...I wont know for sure untill I try them myself but I am very curious...and cant wait to get ahold of a set..

Now I just need to find them...lol I think someone said that flat lander racing (I think) carried Scorpion, but ill have to check...

thanks for the replies, 2wld4u

Check Ebay. I have seen a lot of Crane Gold rockers for $150 and less. I know that isn't what you are looking for, but the point is that you can get a quality rocker for the same price.

Well I went ahead and ordered the Comp Pro Magnums, Im sure the scorpion would have been fine as well as the Crane rockers mentioned, problem is I want to get this together...and the Pro Comps were in stock.... I suppose Ill have to wait another time to try the Scorpion rockers, oh well..
