My Street Demon install experience
So I gave up on the rebuilt Thermoquad and I purchased a new Street Demon 625. I had it up and running within a hour. I called Holley customer support and they sent me the new style Chrylser throttle stud for FREE. My throttle cable bracket didn't align with the street demon linkage. I solved the issue by drilling out the end of the throttle cable and putting it on the same side as the kickdown linkage. There doesn't seem to be any interference or binding this way. I used a tiny E clip to provide a stop between the kickdown and throttle cable.
Idles well around 800 rpm with my lumpy purple shaft cam and pulls about 15hg with the vacuum advance plugged. Throttle response is awesome and I had no issues with my air cleaner hitting the choke or clearance issues with the hood. More pics to follow.
I'm still adjusting the choke to get it to start on the first try. I wired it to the blue field wire on my dual field alternator.
I'm also only able to run about 5 degrees of initial timing at the moment without detonation. Could be old gas or wrong plugs or broken advance spring on the distributor.
