I am just curious if the gains would be worth while to add 1.8 ratio rocker arms (Scorpion) to my Procharged LS2? My car might already have upgraded springs seen by lookin though the oil fill (not an issue if I need to upgrade them if they are stock).

Thanks for any help!

I had good results doing 1.8s on my LS2 with eforce. I don't have the exact numbers but the car was faster at the track. At the time I didn't want to bother doing a cam, which would better route. I don't know about Scorpions, but I am still using the 1.8 Comp ultra golds on my new engine and they have been great. No problems at all.

If you have a low lift cam it can help but I would stick to 1.7 if you have an aftermarket cam/

Yeah, I'm stock cam

I agree. I did it to get a little extra lift without doing a cam. Now that I have a cam, it was spec'd with those rockers in mind.

Very interesting.. I was thinking about trying this as well.
Do you think there might be any gains on a twin
Turbo application with stock cam/heads?

SLP makes a 1.85 ratio rocker arm. At some point, you're going to run out of valve spring though.

My comps are 1.82.
