Quadrajet and Vacuum questions
1986 Silverado, sbc 350 / th350 trans, M4ME Q-jet with electric choke
Motor is stock bottom end, comp cam xe286h with new timing chain etc. Capped vacuum on distributor. I'm wondering if I need all the vacuum lines that are hooked up to carb or if I can cap some. Most are capped except 2 coming from canister to front of carb and one from cruise module to front of carb. Any help would be great. |

Re: Quadrajet and Vacuum questions
Un-cap the vacuum advance and hook it up again. Not using it costs you fuel economy, and doesn't hurt power in the slightest.
