Will you be looking into a version of the rocker arms for standard stroke 289 and 302 engines too?

There's no need for them on a SBF. The adjuster (polylock) is on the fulcrum for a SBF rocker. This is a "neutral" area where weight on the front or rear of the rocker is not affected.

On a shaft mounted rocker, such as on an FE, the adjuster is hanging off the rear of the rocker arm, which puts weight in a spot that's not optimal.

Just to be clear, my rockers will work on any FE, regardless of the stroke or displacement.

I haven't looked at SBF developments in detail for some time, so are you saying that 7500 rpm is easily available with hydraulic rollers?

Yes. That was the driving motive behind all of this. The LS crowd can hit those rpms easily, as well as the Gen 3 Hemis, SBC's, BBC's, SBF's, etc.
