Would 1.8 rockers make much difference? I just had an ARE stage 2 heads/cam package installed and I was sent a slightly wrong cam but rather than deal with trying to get it replaced I had it installed.
My question is the only thing wrong with the cam was the lift. I was under the impression that it was supposed to be a .566 or .561 lift but it came in as only .534. If I decide later that I want more lift can I just go with 1.8 rockers? What would that bring my lift to? If I were to get a new cam I would want something in the .566-.570's. The cam I have now is 222/222 .534 114.
So in your opnion would it be worth the money to get the higher ratio rockers or just install a higher lift cam when the time comes? My main reason for going with this smaller cam is because of smog reasons in Cali.
Also I dont plan on using the nitrous much. Its more of an N/A car.

Re: Would 1.8 rockers make much difference? True, but would it cost more for a new cam and install? Are there any draw backs like ramp rates when gaining lift from rockers vs. a higher lift cam?
Re: Would 1.8 rockers make much difference? The rockers are about $500 by themselves. Not sure what the install cost would be. Stock rockers don't have much resale value. Cam is about $400 but you can sell your other cam for $200.
Faster ramps and more lift put more stress on the springs and may increase valvetrain noise. If you are concerned about that, I would not change the rocker ratio either.

Re: Would 1.8 rockers make much difference? The rocker install would be a snap since I can do it myself and I have double springs on the new heads that could handle .570+ lift so that would be ok. Since I cant do a cam install myself then the rockers would be cheaper.
So either way what you are saying is that lift is lift, wether I get it from rockers or the cam?
Thx for you help too, its making the decision easier if I need to do this. <img src="gr_stretch.gif" border="0">

Re: Would 1.8 rockers make much difference? 1.8s would give you 0.565 on that cam. The higher ratio will give you higher effective ramp rates, although only slightly. Given your situation of not wanting to change cams again, this isn't a bad option, however I have to agree w/ those above about the cost factor. Crane 1.8s go for $650-$700 and the Jesels (which would be my choice) are more than that.

I don't think that's right, but I'm not certain. My guess is that the faster ramp design of the cam will provide more area under the curve than the rockers.
