Ls1 Rocker arm package or ???
If 1.7 rockers are replaced w/1.85 do I really need to change the cam? Of course I would change springs and retainers. Rumor is this setup works and picks up 20+HP and 13 TQ.

For real HP gains, install a set of heads/cam or both. You wont get 20 hp with rockers alone. :nonod:

Re: Ls1 Rocker arm package or ??? (kp)
Kp, I felt the same way(rumor) then the Guy that told me about it faxed me an article from Popular Hot Rodding, Feb 2003 the latest one out.
They took a C-5 LS-1 Changed the rockers w/SLP 1.85 new springs and retainers. The article walks you through the change. They dynoed the car before and after, 2-3 hrs start to finish w/ final dyno Hp from (only mod exhaust)310.6 to 330............... TRQ from 325.2 to 338.5
The car had 60K miles on it.

Re: Ls1 Rocker arm package or ??? (Lashtal)
Is the ratio the same on the LS1 and LS6 ?
I Believe 1.7 is the standard, correct?
Thanks!

A vendor wants to step up and send me the 1.85s...I have the next 2 weeks off, have 2 solid dynos with my current mods (intake and exhaust) and access to a reputable dyno (Mike Norris) for the after results :)

Re: Ls1 Rocker arm package or ??? (GmasterB)
The kit includes rockers, guide plates and pushrods, lists for $900, lowest price I found was $700, factory ZO6 cam and springs can be had for less than $400 and that will get you 20-30 hp and pass emissions...Cam install is a bit more difficult, but is the route I would go, if I were you...

I put a small cam in the car and picked up 20rwhp/tq.. Its possible some years/cams may respond a bit better but there is no way you are going to get 20rwhp from that alone. Try it yourself, I did :) These rockers (SLP 1.85) have been out for over a year, if it was that easy to get 20rwhp dont you think someone may have mentioned it before..
