I have a 383 with the Eddlebrock 2086 Performer Top End kit and I have no idea where I should put the timing with this set up. It is in a 4 speed 68 dart if that makes a difference. Hopefully someone can help. I called Eddlebrock but was on hold forever.

its a big subject that has had a lot of discussion over the history of this site. if you plug in 'initial timing' in the search box above, you'll have a lot of info to take a look at.
I started to toss some links in here, but there are just too many with different mindsets and variations on their engines etc.

there are tons of theories, speculation, and tried and true methods. take a peek and it'll help you along to finding a setting that works for you...even if only as a starting point.

We always start at 14 BTDC and adjust up and down from there. I don't know if you have messed with you mechanical advance but you want to make sure that you don't go past 36 degrees total timing at your top RPM.

Use your ears. They will guide you.

Start by advancing the timing at idle until the engine starts missing slightly, then back off until smooth. If the starter "jams" when trying to start it when warm, back it off a little more. Check the idle timing you end up with and write it down. Then check your total timing. Go drive it warm and lean into it and see if you can hear pinging. Back your timing off until it stops pinging and you find your best high-speed performance. Check the fully advanced timing and write it down, then check your current idle timing. The difference between your optimal idle timing and current is how much you need to limit your total timing.

At my altitude this is critical, even for standard non-performance engines. I set my brother's 1974 W200 360 idle timing and the total was at 60 degrees with the stock distributor and with a stock replacement Mopar unit.

I build a 393 that wanted 19 degrees initial and 29 total with a Mopar .509, 292deg Mopar Purple Shaft cam. Ran phreaking awesome when the cam hit at 3k, and idled down to 800 rpm.
