1.7, 1.8, 1.9 Ratio Rockers for a Series 1
 

How many would be intrested in 1.7, 1.8, 1.9 ratio rockers for a Series 1? How much would you be willing to pay? Which ratio would you want to run?

Sorry not alot about them now but if their seems to be intrest for them I can go into more detail.

I'm looking into rockers right now....but I need to make sure they're gonna work with what I wanna do...

What's the stock ratio?

For more people you may want to get in touch with some ser1 L67 swap fiero guys. There are also a few ser1 L67s on L67swap.com. If they did that much work to put that motor in there chances are good they would do rockers.

They measure at a little less then 1.6's but are commonly called 1.6's.

Ok.....So with a cam....what could I do?

It depends on many factors - lift of cam, stock or modified heads, etc. You need to calculate peak lift. What cam are you looking at and what are the specs?

Valve Timing:
Intake: 22*/64*
Exhaust: 70*/20*

Duration (seat to seat):
Intake: 265*
Exhaust: 270*

Duration (0.075")
Intake: 201*
Exhaust: 206*

Valve Lift:
Intake: .440"
Exhaust: .440"

Power Range: 1800-6000 rpm

Blazin, is this a 'known' source, a bypass of the middle man for a known source, or a new source for us?

Watching this topic with interest. It's either a cam or rockers for me next, and my cam was going to be custom.

I would like to see what you would come up with for cam numbers Bill...

Eh those cams... With 1.7 rockers you will have a lift of .467", with 1.8 rockers you will have a lift of .495". I think that Jay is runnig that cam with 1.72 rockers.
