    Which one!!

    Ok people, I have another question. If I was going to replace my rocker arms, which ones would you recomend. The rocker arms I'm looking at are the Com Cams non-self adjusting 3/8". And ws6store.com has them in 1.5 and 1.6 ratios. That is where I would be purchasing them from. Which ratios would you guys suggest?

    Just a reminder. It is going into an 02 ws6. And I have put a Texas Speed 233/239 .595"/.603" 111 LSA cam in it.

    Stock ratios for the LS1 is 1.7. I'd stick with that, especially since you are already running a .600 lift camshaft.

    With that said, lots of rollers out there to choose from. I prefer an adjustable drivetrain, my wifes car has a complete Crane roller rocker system that eliminates the rocker shafts.

    I believe there are rockers available with the same roller fulcrum as stock, but with a roller tip that will adapt to your stock shaft assemblies....

    Well, I talked to Mike over at ws6store. And he recomended theYella Terra Ultralite non-adjustable rocker arms. He said that they were the only ones they sale that are a direct replacement for the stock rockers. He said they were the exact same size as the oem rockers. He said they are available in 1.7 and 1.8 ratios. So I went the 1.8 ratio rockers.

    I really appreciate your input Firebirdjones. Thanks a bunch!

    Yella Terra are a popular brand that should treat you well. I assume you realize with the 1.8 rockers your lift jumps to .630/.638

    Well, yes sir, I did. I knew it would raise it up about that much. I haven't had a chance to calculate exactly how much. But I knew it would be in or around that area.

    Personally, I would have stayed with stock (lightest all) and a cheap yet very effective trunnion upgrade. Don't think I would have stepped up to 1.8 either.

    The stockers are a great piece.

    Well, the thing is, I had to go with a new set because I was seeing some wear on the old ones. But it's cool. I do want to try the 1.8's.

    Roller tips are a nice addition, especially with a cam that size, valve guide wear is always an issue. I prefer full rollers, too bad GM didn't incorporate that into the stockers. Otherwise I agree with hi-po, there are a decent piece.

    You're right FBJ. That would be nice if GM would have done that.

    the lift in my sig is the calculated lift with the 1.8 rockers
    2000 ss camaro, forged lq9 370 short block, stage 3 PRC 243 heads, fast 102 w, big mouth throttle body, MS3 cam, 1.7 roller rockers, stage 3 t-56, monster stage 3, pro 5.0, 4.10's with moser axles, bmr tq arm, lca's, phb. SOLD (thankfully)!!!

    Having a small cam is like having a small dick, everytime you go to use it you wish it was bigger
