Vacuum advance removal, is it possible?

The only reason you have to get rid of vacuum advance is to satisfy ignorance. You can have a vacuum advance canister, hooked up and functional, on any vehicle, race or street, with nothing to lose. In fact, on your street car, your motor will live longer and you'll get better fuel economy.

Fact is, at WOT, vacuum advance does nothing. Zip. Zilch. No vacuum (as in, at WOT), no advance. End of story.

At cruise (no matter how bad *** you think you are, if it's on the street, you're in "cruise" mode most of the time), you get a cleaner more efficient burn which means your rings live longer (less fuel wash) and better mileage. It's there for a reason! You like how the EFI motors live forever without needing ring jobs at 100,000 miles? That's due in large part to reduced fuel wash. Seriously. Look it up.

If your motor doesn't run well at cruise when you set your timing to whatever mark on the distributor, you need to tune your distributor, just like you would anything else on your car. Advance springs and a twist o' dist aren't all, you can control the amount of total advance by swapping advance canisters, and the rate of advance by an allen wrench in the vacuum nipple.

So, it does NOTHING at WOT so it won't hurt your performance, and it helps your motor live longer and make more response and economy at cruise. Reason to toss it? NONE.

If you insist on removing it, I'll pay for you to ship it to me! Just unscrew all the screws in the trigger plate, lift the plate up to unhook the arm, and unscrew the advance canister. Presto change-o! I keep a myriad of vac-advance cans around to tune with, and can always use more.

If you've seen the light, there's an issue of Mopar Action from '99 (I think it has a silver 300C looking droptop on the cover) that covers it all.

And yes, there is NO advance in a lean burn distributor. If you want to be super trick, you can hunt down (or buy at Autozone) the dual trigger plate. Flip a switch for bad fuel/race fuel, tow, or nitrous modes!

The main upshot of expensive distributors is ease of tune-ability. Your factory Mopar distributor has all the same functions, they're just not as easily accessible!
