I haven't driven it yet so I can't tell how that combination would work but I drove with the .68 for 2 years and would not do that again. Sounds like a great project - you need to share pictures as soon as possible.

I have the 3.54 ratio with a TKO-600/0.82 in my ERA 289 FIA. I've very happy with this combination, and picked it after studying the TKO-600 0.64/0.82 threads here on CC (nearly a decade ago...).
I'm sure Bob at ERA could offer some sage advice here.
