Rocker arm weights Scorpion vs Comp. Come inside I was going to use the new comp Ultra Pro Mag rockers on my cam swap but I've started looking at scorpion and they look pretty appealing too..
Both offer a lifetime warranty and both have a new line of rocker that is lighter than its predecessor while retaining the same claimed strength.
Soo... I am looking for the actual weights of any of the following rocker arms.
1.6 SBC 3/8 or 7/16 stud NSA
Comp Pro Mag
Comp Ultra Pro Mag
Scorpion Race Series
Scorpion Platinum Series
The ultra pro mags claim to be "26%" lighter than the normal pro mags.
The Platinum series scorpions claim to be "20g" lighter than the Race Series.
The Comp rockers are chromoly whereas the Scorpion's are aluminum.
Basically I dont want a rocker that's heavy over the nose, even if the respective total weights are the same. By looking at the design of each it looks as if the ultra pro mags may still win out, since they have such small mass near the tip, and the un-needed material due to x-bracing has been removed.
The price difference makes the scorpions very attractive if performance is going to be similar. Again they are both lifetime warrantied.

Honestly, weight over the nose is not nearly as important as the quality of the entire rocker. You should buy a rocker for the quality of the roller fulcrum and overall construction as opposed to the weight over the nose. And even if one rocker had less weight on the roller tip, I cannot imagine the HP/valvetrain effects to be even measurable, especially at your power level.
Like I said, there are more important things to be concerned with.

How do you know the Scorpion is lighter over the nose? They only compare the weight to it's other in the lineup.
Look at the size of the bearings that the rocker itslef pivots on. That's a no-brainer for me. The Comp piece looks 5 times as strong. The Comp's bearings look to be about 2/3's of an inch wide, while the Scorpions look like a No2 pencil width.
