I wanted to chime in here. I have a 67 GTO with a 68 Q-jet on top. It's a divorced choke. I'm running 6X heads as the 400 has been stroked to 461. The exhaust crossovers have been filled.
I was looking for an electric choke conversion but just wasn't thrilled with what was out there.
So, I tried something a bit different.
I found on Amazon, some heating film that happens to be the same size of the choke stove base. I fastened the film to the manifold base and secured the choke stove on top of it. I wired the film into the wiper circuit. The film heats up to about 400* F and it causes the bimetal strip to open the choke fully in about 5-6 minutes.
Here's a link to the proof of concept video.
