rocker arms I was speaking with the shop mechanic today(he also owns a speed shop)
He was telling me that comp cams cam out with some rockers arms at idle they are 1.74 then at wot they go to a 1.85.
I cant find any info on such lifters I'm not thinking of doing this to my car if they don't exist i want to call his bullshit, If they do i want info on them since they sound interesting.I guess they were made to help a ls1 idle and for the guys that want a sleeper car

No prob. They actually start out at 1.8 then revert back to 1.72 at around .300" lift. Then they go back to 1.8 on the backside ramp at around .300
Pretty slick upgrade for a stock cammed car.

My ls1 just got over the burps and tantrum of having a cam upgrade so no way in hell i plan to touch that motor. it is going on 3 days running just smokin *** hot.
so what would the lift be on a stock cam at WOT I don't even know what a stock cam is never paid any attention.
might be close to .500 on the exhaust side, but I doubt it. lift is the same at all throttle positions.
the stock cam in my car has these specs:
197/207 int/exh @ 0.05" duration
0.467" / 0.479" int/exh lift
116 LSA
with those specs the lift under .300" is going to be accelerated to .507 on the exhaust side and .494 on the intake side.

you can call BS on the fact that they change rate dependent upon throttle application. Likely just his misunderstanding of the technology. As you've already figured out, they change ramp rate independent of RPM and throttle application.

Hello........Ok guys...it's just a marketing ploy.....I mean seriously come on....
Our valve train is not in a true verticle position (from the lifter)....Even if it was the rockers we use need to swing on an axis were the push rod contacts the rockers, in order to keep the rocker ratio constant through it's arc. Almost all rockers (including ours) are varitable ratio....The ratio that is stamped on a aftermarket rockers is the minumum ratio through it's arc. Crane cams can
kiss my *** from now on, with this BS ploy 
Crane cams............... for general knowledge here.....the stock stamped small block chevy 1.5 ratio...usually measures out to 1.38 to 1.46 ratio through it's arc....
Oh, I guess crane cams can grind a specific cam for the small block chevy "Stock" varitable rocker too........what's next cam specific grinds with this OLD...I mean new technology......

Hey Jimbob, it's better than their "NEW" beehive technology for valve springs! 
That said, you need to talk to Ellis before you do anything like this slowpoke. Stock rockers are 1.7 ratio. I am running 1.8s. But most aftermarket rockers, while 'better' than the stock ones, can create issues of their own. Like not clearing the valve covers, or making the valves hit the pistons, or insignificant things like that.

I have came to the conclusion as hard as it is the next car will just have to have a cam replace. Not as beefy as mine cant have my wife with a faster ride
I'm looking high and low into a new car the durango is **** up. the local machine shop wants 500 per head to resurface and install new valves and seats.This does not include if any cracks are found.The bottom end needs work too so i really only have a few options left at this point and only 2 weeks to figure it out and get it done.
damnit logged in as my wife again
