I set at 10 idle with the shunt. With the shunt removed I’m at 18 degrees at 900 rpm. I’m running Sunoco 93 octane. I verified my tach is going wacko at 4000 rpms, and it starts to pull harder and rev out. I used the new timing lights built in tach and I reached about 5,000 rpms in this video. Sounds healthy with no knocking but could it be causing damage? https://drive.google.com/file/d/11TguC7qvluonjEvg5gU3OEuylHMHzk_j/view?usp=drivesdk |

Hi Mav
I think I'd back it down to 34 to 36 at 4000 rpm. Maybe more depending on gas being used Did you set the initial timing at 10 with the timing shunt installed ? |

I upgraded to a Delco EST this summer on my 454 h.o. I’m wondering where I should be at for timing?
I bought a new timing light with a tach to check the advance. I’m running 30 degrees at 3,000 rpms and 38 degrees at 4,000 rpms. Does this seem a bit high? No pinging noise or evidence on plugs. |
