Seriously not trying to bash but, isn't the longer duration of higher ratio rockers pretty negligible? I understand why it would. It opens the valve faster and closes a little later. But that'* not close to the thicker lobes of a mild cam.
I dunno i just think rockers = larger lift and cam = larger lift and longer duration.
Either way the rockers will probably keep the computer happier.

I can deffinately have the money in one month a 6 days. I have been dying to get ahold of these, and they fit perfectly into my whole plan for what i want my car to be. ITs impossible for me to get the money any sooner because a lot of things have changed lately, i got a better job, but there was a period before that where i didnt have much money and i had to catch things up,: on top of that ive already commited to purchasing other things that i need which arent related to the car and i have to fulfill those commitments first. Im practically begging u to let me in on this, even if it means having 6 people, i just need the time

I'm working on the details of that right now. I'm expecting to have them all shipped to each house straight from the manufacturer.

95naSTA - You're generally right to think that way. I was really trying to illustrate the point in a way others could relate to. The actual gains in duration will be as much as 4deg. If you look at the crow cams, you'll note the difference between their baseline cam and the "medium performance" cam is 3deg on the intake and 6 on the exhaust. You'll also notice the valve lift remains the same between the two at .440". Assuming a stock cam lift of .250" these rockers will give you a valve lift of .430". .010 shy of their "medium performance" cam, which is why I used it to illustrate my point.


Jachin - The reason I'm suddenly pressed to get these is because I have a deal with the devil that allows me to buy them. Being the devil she is likely to change her mind at any given moment because she wants to fly out to Maryland or we just "have to" spend a week in Canada or any number of other "engine performance inhibiting" adventures....I've said too much In any case, like I've said before if you can't get in on this deal won't worry, I'll put a lot of effort in negotiating the minimum price possible for future purchases. It may be possible to maintain these prices if I can illustrate a real demand for them and a steady flow of buyers. Hope is not lost

Note, these will work with Roller Rocker Series I engines.

Not all 92'* will accpet them, unless you buy some other heads. (not a bad idea)

Yeah I rememeber Jef..er.."Former Member" having to do some work to get the '93'* to work on his '92. As I remember it was because of the stud sizes. These rockers are available in 5/16 and 3/8 stud sizes.
