Timing Ignition (How-To), And why Duraspark Sucks.

Rattle, rattle?

Coil packs.

Ah! LS?

Nope.

I cheated and searched. Nice 5.0 swap.

Good morning guys,

I feel silly asking this, but where should I hook up my vacuum gauge for setting timing and advance?

Greetings, any manifold vacuum source will work. Either off the manifold itself or at the base of the carb. You know you have found a manifold source if it shows vacuum at idle.

Not sill, the vac system is kinda a mess on stock set ups.

There are usually fittings in front and behind the carb and depending on year the brake booster will share the fitting with a smaller nipple, one of those would work. I'd do the one without the brake booster line.

Thanks fellas. The DUI distributor, new plugs, wires, and vacuum gauge came to day. I made a lot of headway with the wiring (relay method) for the hei, removed and installed new spark plugs and wires. I didn't feel right hammering away at a $300 distributor so I am taking the new and old distributors to a machinist near work to swap the gears.

I ran a tee on my front ported setup. At any time (like just now), I can easily hook a gauge to it and play with stuff. Just finished setting timing. I have a slight exhaust leak, so I'm always getting a light ticking noise. Advancing the dizzy proved to me what detonation sounded like. I ended up getting a tad more advance than what I was running. No detonation after hooking the vacuum advance back up. Should be good to go.
