So your "new" exhaust manifold doesn't have the heat well your old one has?
I'm just finishing up converting my '64 Slant from the stock 1920 Holley and exhaust to a BBD two barrel carb and Clifford shorty tube headers. Not having the factory heat well anymore, I cut up a piece of scrap 3/16" steel plate with a Harbor Freight grinder and made this mounting plate for the heat well electric choke conversion I was already using on the Holley 1920.

I've read that my 1920 electric choke spring rotates the wrong direction to work with my new BBD. Once I reconnect the battery power and I prove that this electric coil spring won't work with my BBD, I may have a deal to offer on this 1920 electric choke.
