When you say "Kafer brace", you mean the pickle fork supports that bolt to the shock towers, I assume?
I don't want to hijack the thread, but your build is nice enough I would like to get your opinion... I have been debating on how to finish my engine mounts in my "Not Aunt Bea" '66 and I already have a new Gene Berg rubber isolated traction bar. Do you like the Kafer braces better than a mid mount, in conjunction with a mid mount or do you think either is fine up to xx hp?
I'm planning on a 2275 with 48s and a moderately aggressive cam and timing, but not too much compression. 42X37.5 valves and a semi-aggressive port job should finish up the job. I'm thinking Berg's mid-mount, the traction bar and either the firmer stock mounts or urethane mounts along with that. Whatcha think?
