I have been looking into getting aftermarket rocker arm. Does anyone know what the stock rocker arm (ratio?) is? I assume they are 1.5. I've read that if you put 1.6 it's good for 10 hp. To me that's a pretty cheap mod with a preety good gain. Let me know what you guy's think.

Go 1.8's, SLP sells them and they are very nice pieces... I'm starring at them right now! (for another customer):cheers

 

[05_HUMBLER]

Sounds good. One question; will I have to replace my push rods or lifters? Thanks for your help

 

[GTODEALER]

If you do the rockers, no, the only thing I would recommend is replacing the valve springs to something that can take the added stress, problem is, once you do both you can buy a cam cheaper.

Thanks, what type of springs would work best?

 

[GTODEALER]

SLP sells a kit, you can check it out on www.slponline.com:cheers

Stock is 1.7 ratio, according to SLP's web site

1.8 rockers

All lot less money would be to use the LS7 1.8 ratio exhaust rocker. Something like $144.XX + Tax + Shipping for a set of sixteen. p/n 12579617

And LS2 GTOs have LS6 type springs. Good for the additonal lift the 1.8s would supply.

All you need are the rocker arms.

It's going to push the lift to .600 on the intake and .596 on the exhaust, you NEED better valve springs!!!!! I'll sell the LS7 rockers for 144.00 + shipping + tax, but you still NEED valvesprings!

I'll take your word for it! Can you give me a good price for rockers and springs?

PM recieved Thanks

Correction.

Other fellow is correct. These springs are apparently good up to the lift of the what LPE includes with the GT2-3 camshaft. Which has .571"/.581" lift.

I would have sworn LPE advised someone the springs were good to .600" but cannot find the citation. Better safe than sorry.

You are right sir :cheers

I know this is an old thred, but has anyone else heard of this? Will the LS7 rockers fit the LS1?

 

[05GTO]

Call Steve aka. Gtodealer, aka. Radio, you will find his phone number in this thread. He knows his sh*t when it comes to the LS1.
