Thread: ZZP ER Rockers w/ Yellow 90 # springs

Im selling a set of ER Rockers with 90# yellow springs.

I guess these are different than the 1.9's (Intake 1.85/Exhaust 1.8).

If needed, i can also throw in some reusable rocker bolts.

$230 Shipped

Are you sure those aren't 1.85 and 1.6? Also can they be swapped for higher ratio on the exhaust?

Thanks

Jeff

Im not sure about swapping intake and exhaust but i dont see why it wouldn't work. Im assuming you would get the best flow from using the 1.85s on the intake and 1.8s on the exhaust.

I am pretty sure he has 1.9's all the way around, as we've been talking about them.

Boosted Pontiac you list these as 1.85 and 1.6 originally, and in looking at the pictures they look like they are 1.6 as the hole is too far away from the first pic to change .05:1 ratio as yo can see that a 1.85 and a 1.9 are almost indistinguishable from one and other. It would be better on a Supercharged engine to add lift to the exhaust since it's harder to get the air out than in, but I was just wanting to clarify what ratio these are. When I compare a pic of a 1.6 it looks the same as the bottom one you have shown and when I compare 1.8-1.9 they look much more like the ones you have on the first picture.

Thank you,

Jeff

The stock 1.6 ratio pushrod hole is farther towards where my thumb is. I can get pictures next to a stock one if you want to show you that they are not stock.

Stock series 2 is far right

Ok, let me think on it for a minute as I am conflicted about just getting 1.9's and this is a good deal.


Jeff

Are you supercharged or NA?

supercharged. And yes I understand.

Sounds good, just let me know.
