Roller Rocker Arms

**lonewolf37** · 06-12-2006, 07:39 PM

I am considering a set of roller rocker arms for my 2001 Z28. I see a lot of suppliers out there. SLP sets are about $500. I need input on what to avoid.

I would avoid everything man.

The stock ls1 rockers are fine for almost any application. I would just cam the car and be done with it. 500 is alot of money for very little gain.

i bought harland sharp and have had no problems.i think i paid 365 or so.the stock rockers are good enough though.i've seen 1000 hp made with stock valvetrain.

not all rocker arms are useless. depends on which ones you buy. i use the vinci/crane 1.8 accelerated lift rockers on the wife's car. this is a dyno back when it had the stock cam.

dyno 9 before
dyno 11 500 miles later
dyno 14 10 months later

be careful with accelerated lift rockers with a higher lift cam. dont really need that at all.

I allready bought a set of Crane accelerated lift roller rocker arms, got them on ebay. My new set up will include;
SLP Cold air induction
K@N Filter
SLP Airbox lid
Granatelli Mass Air Flow(W/cold air tuning)
Throttle body bored out to 78mm
Crane roller rocker arms
JBA Shorty headers
SLP Y pipe
160 Thermostat
Throttle body bypass
reprogram with a Hypertech 3
I wonder how much horsepower I will make?

I was hoping for more like 100hp increase.

Won't happen.

There have been some cases (believe it or not) where people are actually losing power in the upper rpm range with high ratio rocker arms. There have been a couple of threads about that in the *other* forum.
