Coming Soon: Higher Ratio Rockers

[Nick-G]

I know. suffice it to say, things are happening fairly quickly. in a very good way. everyone will know more soon.

That's great to hear. I have money in hand right now that I'm saving for a set of these.

[drayrunner]

avaliable

Anyone hear when they should be avaliable

[gectek]

ATM the sets will only be available in sets of 12. that should change after a little bit though. progress is being made rest assured

[ForcedFirebird]

Production date on the 8mm heads with 1.7 ratio?

I know I'll be taking at least one set of 6 for sure (working on a customer to buy a set of 12).

[drayrunner]

If they are in the 300 range and 1.8 ratio i'm in for a set, as far as a delivery date, they just tell you what you want to hear,And yes i did send a email. oh well i guess we should consider ourselfs lucky they are making rockers for the 3100- 3400 motors.

[SE'sarecool2]

Count me in too. I've been wanting better rockers for a long time now.

[geldartb]

im in for a set too. you can count me in for sure.

[montess408]

yeah i would like a set in the second half of the year. will they be avalible in 1.7 and 1.8 ?
i would be interested in a 1.8 set. and there is no need for custom pushrods right ?

[Nick-G]

I'm for sure in for a set.

Well then count me in. If you have any advice on a stagger or sizes or anything I would really appreciate it. I am running ported heads and intakes with comp springs and SI valves on my 1393 cam, along with all the other bolt on stuff.

[gectek]

educated guess for 1.7 would say 5-10 across the entire operating range

guess with 1.8 is prob 10-15 ish.

staggered ratio would be good too, but kinda hard to say. real world results would depend on so much. cam selection, ramp rate, springs, head flow rate, intake flow rate, exhaust flow, tuning, engine management.

its really complex. ill say it like this. from what i have seen published and in real life, bolt on a .1 point change in rocker ratio can range anywhere from 5-10 over a stock valvetrain. IF you were using a ball style stamped steel rocker like the SBCs then its even more than that. esp if you jump from a 1.5/1.52 ratio to a 1.7

[alerored04]

Well if that is the case then I am in about 90%. Just need a guess on power gain on top of my cam.

[torq455]

locked in. like i said, in the near future, say between 2-6 months.

[gectek]

lift for the most part has no effect on drivability. you will prob see more off seat duration, but it is not going to add more than a couple degrees. it really isnt measured like that, but that is really the simplest way to put it. the only thing you would have to watch is coil bind. you may want to tune a little more on it, because it will have the chance to fill the cyl during the intake event and move more air. you could prob add more timing and it might change the VE a little, but seriously if you have a MAF, it should be able to compensate for that.
