My car's exhaust fumes are bad enough at idle to bring tears to your eyes.

Idle is at 800. Timing is 12 intial + 21. Intake vacuum is 15".

Carb is a Holley 650 DP with 64 & 67 jetting. Seems good.

I changed the Power valve from 6.5 to 10.5 and that helped some.

Increase initial timing?

Is this condition being caused by the short headers?

Any other suggestions or is this the nature of the animal.

Thanks,
Bud
