|aprilworkheiser||Thank you for this wonderful knowledge base entries. I love to read more from you guys though this thread hasn't been updated yet. I've been searching for so long over the internet regarding the list of distributors. Thanks for reposting this entry!|

Great thread.Thanks Rick Wi.
(I know that it is old,I was searching and thought it would be a good one to bump for folks that have not read it)

|cuda66273||Or turn it over to a professional and have it done correctly, on a distributor machine.|

|Rhansen||If running vac adv from a manifold source the can will give full advance on deceleration (i.e. at the end of the 1/4). Is this hard on the motor?|

Thanks Rick. I know someone around here had said something about that and it got me thinking. I just wanted to know what it did. Again thanks great post by the way very useful.

|Rick WI||Yes moving the wires on the terminals would be like stabbing in the distributor one tooth off.|

Let me ask something here. You know the so called old red neck way of moving the spark plug wires one over in either direction on the terminals. How much timing does that acount for. Would it be kinda like moving a dis. one tooth or two? I mean I know you then have to turn the dis. to get your mech. adv. but as far as int. goes if you move the dis. how much does that effect timing? SOmething I have been wondering.

Although I don't use Pertronix that is the type of distributor (electronic) you'd want to use. You would not want a points type.

The real meat of the entire thread is that regardless of what means you use to provide spark lead to your engine, your engine is going to like a specific amount of timing under specific operating conditions (for ideal combustion burn). This is going to be a trial and error process for each individual vehicle, but with the information available, one should be able to design something that is close to ideal, and could be fine tuned to perfect the entire curve.
This thread by Rick W is pretty much how I've always done it myself, and it's not a difficult process to comprehend.
In this day and age of EFI and DIS, it's not that common anymore to find mechanics that can tune older carbureted, distributor type engines.
I've seen tons of fresh tune-ups that ran like crap. Many of them run poorly because somewhere in the fray, the engine's spark advance was plumbed into ported vacuum. The difference between the two in my experience has been night and day, and I have ALWAYS used manifold vacuum, even when the if the factory used ported. The sound of an engine's "sweet spot" is readily evident when you get it right. Anybody can tailor their own custom curve if they've got an advance timing light or timing tape properly installed, and a vacuum guage. No black magic involved at all.

WAY over my head, shewwww
Ok, a little help here...
This article completely hypnotized me.. And what i got outta it was, dont buy that new Pertronix Flamethrower that was recommended in the 383 stroker article ive followed for my build?
And i should go and buy the distributor w/points and use the vac. control can you suggested?
I dont mean to sound ignorant, LOL but i am at this point, but im reading...
I need a little clarification... in a more layman's term...PLEASE..

|Jmark||Well, I think my sons adjustable light is still here so I'll go give it a try. I'll double check the mechanical and total again. I redid it a week ago when I noticed my weights had gone stuck AGAIN fully advanced. Getting tired of pulling the dist and tearing it down and cleaning the shaft!|
