Ford FE rocker arm ratios

[JackFish]

Can someone tell me if there are FE series rockers that have the same 1.52:1 ratio as the stock 200?
I have a line on some sets, and I seem to recall that the FE series came in 1.6 and 1.7 ratios, or something like that?
I don't want to pick these up if they are the same as the stock 200, so is there a way to measure or determine the ratio of these arms? Perhaps some casting numbers?

Not even close. I not100% which one is which but there are 2 ratios
Non adjustable is 1.72 and adjustable 1.76 I think.

do the FE rockers fit the ford 6's?
do you need the whole FE rocker shaft and posts ?

or do you fit the FE rockers to the fords shaft and posts

allways wondered....

I've wondered too, so that's why I'm going to have a look at these.
The shafts are obviously shorter, but I'm hoping they're the same diameter.

I've been looking into using FE rockers as well, I've got a set here. The rocker shaft is much larger than the I6 rocker shaft. I've also looked into using 1.6 ratio roller rockers for 318 mopars.

So there's no way those rockers will work for an I6?

JackFIsh,

Nothing is impossible. I looked at doing this at one time. There is simply too much wrong. You would have to either bush the FE rocker down or use 2 FE shafts pieced together. The distance from the center of the shaft to the valve tip is off quite a bit so new shaft stands would have to be machined offset. It seems like the push rod on the FE comes in at a different angle than the I 6. The alignment of the tip, shaft and push rod adjuster is way off. I'd look at a different solution.

Great, thanks for the confirmation. I won't pursue it.
