Doug&Deb Posted October 16, 2021 Report Share Posted October 16, 2021 Here’s a twofer question. First the plugs. I was asked about them in my thread about timing. I’m running Autolite 295’s and they look normal to me with a tan color and no oil. Second is the crank nut. I’m tearing down my spare engine and I can’t break the nut loose. Dumb question but is it left hand thread or am I just really weak? Quote Link to comment Share on other sites More sharing options...
Sniper Posted October 16, 2021 Report Share Posted October 16, 2021 It's not left hand thread, lol. A good impact can knock them loose. HF sells a decent battery operated one if you don't have an air compressor. If the engine were still in the car I just use the starter to break it free. 2 Quote Link to comment Share on other sites More sharing options...
Doug&Deb Posted October 16, 2021 Author Report Share Posted October 16, 2021 Got it. Couple seconds with my impact then a breaker bar. The plugs were wrong. I was running non resistor plugs with a .035 gap. Oops. Installed 306’s and it’s good. These flatheads really are forgiving lol. 2 Quote Link to comment Share on other sites More sharing options...
