New Scorpion Performance Roller Rockers?

**Sunset T/A** · 07-14-2007, 12:16 PM

Anyone have them installed yet? Can you give me some input on how you like them? Any gains at all? Do you have to change valve springs on a stock motor? Thanks.

A guy on Corvetteforum just had a huge problem with them. I would tread carefully until he finds out what happened. Looks like he may have had a setup issue, but at this point there is no word on what happened.

I looked at those pics and to me it sounds like someone didn't check their pushrod lengths.......dont know if I would go so far as to call them crap right now...may be more user error on that particular install......

If it happened on start-up I would tend to agree, but he had some miles on it. It is FI so I can only think it ran good but he was floating the valves and the rockers got pounded. That said, the fracture surface on the aluminum doesn't look like an extrusion, more like a casting.

read the thread. he said he had 8000-9000 miles on them. pushrod length, piston to valve clearance issues, etc... would have shown up alot sooner.

Read the thread....he didn't even know what ratio he had......trust me.....if the pushrods were just a little off it could of made that damage over time......could of made it 8000 miles but to have every last one of them do the same thing........sounds like an easy answer.....but hey.....wont be the first time I'm wrong...

He isn't updating the thread. My gut is telling me that since he is FI he didn't do much to upgrade the valve train and may have been floating the valves. He doesn't give any indication of power loss though. Have to admit that this is the first time I have seen this with the Scorpions which are running on a number of LSx motors so his failure really doesn't make sense. There has to be more to this story that we don't know.

That's what I was thinking....something just isn't right......I've seen a few cars running them and nothing like that....but hey...anything is possible......I use the Harland Sharps and love em........

they would have to be alot off and causing coil bind to cause that.

and i've been wrong many times. hopefully we'll see.

I was going to bring up the corvette forums threat. i would avoid them.

It think its an install issue.

I have these on my 2000 Trans Am, WS6, LS6. I have the stock ratio which is 1.7 and they bolt right on. I did feel a difference. I could tell I had more pulling power and I gained .2 in a quarter mile with the Scorpion rockers.
