Hello, Thanks for all the info, I put a brand new Holley 600 carb on it that I had for another project, It did the same thing, once it warmed up it wouldn’t idle and headers started to glow red ( but not as bright) but it took a little longer to do so. I’m using MDS 8.5mm super conductor wires. I normally run 91 octane unleaded and mix it with 101 octane unleaded about 50/50 but this time I used a more of the 101 octane, this the only thing different I did before I drove it.. My vacuum at idle is 10” do to the cam size. My timing light died on me, when I get my new I’ll check it. Also I’m trying to make up a propane tester. Thx everyone
