I have a 30' long x 6'4" high 12" wall I have to pour up against an existing hollow CMU wall. Normally would just use coil rod insert's and loop tie adaptors to a Symons panel if it was a solid wall. I proposed using a Hilti screen and epoxy coil rod and loop ties and the engineer does not want me to tie into the existing CMU wall. I know they make steel A frames for this application seems like overkill for a 6'4" wall. I was thinking a whaler at the top and bottom with a strong back every 4' and a 45 degree kicker at every strong back. Has anyone done a form like this or have any suggestions?

Seems to me you are on the right path with the whaler, strong back and kicker plan. Maybe a whaler in the middle as well just for fun. Its easier to have more bracing than find out you need more in mid pour.

We typically use the coil rod method also. I'd say add another whaler and you're on the right track, just throw some extra bracing in for a little security.

Just remember, when you only form one side, think twice the pressure. Brace the h*** out of it!

Why did this have to be done? Bearing for a new extension or was the block unstable? Seems like the block had to be in good shape to hold the p wet concrete back...

Just wondering

Looks good. We did somthing similar on a ranch home, we were adding a basement addition and had to underpin under the footer for these 8' walls. Pretty much did the same thing only with gates.
