Scorpian, Yella terra, Or Harland Sharp rockers?

Which is better? About a $100 difference amungst them all but I am leaning towards the Scorpions because they are the same color as my car (Blue)

and I have read and reasearched that they are great rockers. They are also the cheapest. I found some for $349.

I have the comp cams rockers on my Big Block and have had no issues with them, but they are real pricey for the LS1 and I don't want to change valve covers.

I personaly like the Yella terra's I had them on my stock ls1 and now have them going on my 408. If nascar uses them and feels safe with them going 200mph all day then I feel extremley safe with them too. I gained 9rwhp and 8 lbs of trq from my stock set up. they are not extremley pricey either and are sema sponsered product... But as you stated they are not as pretty ads the other ones... kidding...haha

I am a big fan of them Hot Rod magazine had a big write up on rockers, and they pretty much said they loved them. they stated that this is racing technology from the track to the street. So, it sounds pretty good to me and I am a big fan of Hot Rod magazine and the write ups they do....

I installed the Scorpions on mine and they were very easy to install. I really don't care about the color because they are covered up by the valve covers anyways. Price was cheaper than the rest and so far, no issues with them. I am not sure of the added HP performance but I was running 12.9 in a quarter mile at the track with the stock rockers and after Scorpions, I was running 12.7's.

Was this with 1.7's? Waht other mods did you have?

Don't forget to mention Crane Gold Roller Rocker Arms. A little pricey, but they come with pushrods. I use them with a 1.8 ratio. 30K miles on them, and they are smoother than ever.
