Jody, what's the plan for linkage? Are you planning on a a rod end / link / bellcrank system to tie both TB's together and then using a single cable to work the bellcrank?
It's hard to tell in the photos but are the TB's feeding seperate plenums for each bank, or one common plenum? If it's a common plenum having the TB's slightly out of sync wouldn't be a big issue, but if they're each feeding a seperate plenum then I'd want them as sync'd as possible!
Looking good...
