if you have 35 degress at 3000 rpm that is your total timing
all parts are sold as is, all parts are considered used no warranties or returns paypal/check/money order, shipping is from zip 02891, buyer pays paypal fees 24% IRS 1099A plus 3% of part price, check/money order preferred site is not monitored 24/7 there might be a delay in response

Yes sorry the whole while having the vaccume advance plugged off. And yes i have been told its time for a re-curve how do i do that? and where can i buy the parts for the mopar electronic distributer with vaccume advance? And i wish somone whould answer my original question, with 8 degrees initial timing and 35 degrees mechanical that is a total of 43 degrees total timing, is this too much timing while running 91 octane? i have not heard any pinging under load so i'm guessing i am not hurting anything running the toal timing that high because i am running 91 octane fuel.
SLOWLY re-read my post until it makes sense. I did answer your original question. 35 is you total timing, not 43.

43 is on the high side with todays gas even if you dont hear it ping. but 35 at 3000 is your TOTAL timing

you subtract initial (8) from the total (35) to get the mechanical amt (vac adv capped as you said). I'd want more than 8 initial which means the slots will need to be shortened to maintain the correct total which MAY be 31 instead of 35 on a magnum. With that finalized then lighter springs staying just under the pinging point at WOT then plug in your vac adv & staying just under the pinging point at minimum part throttle (high vacuum) at an RPM where the slots are maxed out as in out on the highway at a light throttle cruise. EDIT the light spring kit will change how fast the mechanical adv comes in & shortening the slots will reduce the amount of mechanical adv

Lazy or uneducated. There have been a TON of guys come on here who've built solid 350-500hp engines. And so many of them have that deer in the headlights response when you ask them what they've done to the ignition curve. Seems nobody wants to touch the distributor but will gladly chase the problem around by playing with jets and squirters. Stock distributors had lousy curves for stock engines, never mind modded ones. If that was my engine, I would do the following: Warm the engine up good and hot to normal operating temp. Pull out the timing gun and set the timing at 10*. Shut off and see how it restarts. Repeat this procedure while bumping the timing up by 2* at a time until the engine starts fighting against the starter. You will know by sound/feel. Then back the timing off 2 degrees and see how it restarts hot. When you get it to start fine again with as much initial timing as possible, THIS is your initial timing. Then shorten the advance slots to get 34-36* or so total timing. I think that's what magnums like. Too much timing can actually make less power, even though you don't hear it pinging. Typical small blocks with open chambered heads will take more timing, like 36-38. Different springs will adjust the rate at which the advance comes in and the rpm total advance is all in at. You can have total all in at 3000rpm or at 2000rpm depending on how you set it up. In a 4x4, you probably don't need all the timing in overly early if you're going to be putting a load on it while 4x4ing. But get your initial set to where it should be, probably in the 12-15 range and enjoy increased throttle response, cleaner burn and better low rpm power.

Ok, so i advanced the distributer to 12 degrees and it still started so i went to advance it a little more and the distributer would not advance any further then 12 degrees, whats going on here? the distributer is not hitting anything ether? i dont get it? is it possible my old man put it in there to where it could not be advanced any further then 12 degrees? do i need to pull it out and put it back in at a different position?
I believe you can rotate the distributor back the other way and move your wires one position would be the easiest, than start over with the timing to get to where you want it. but others know more than I do. Probably didn't explain that very well.
