I think I have mine at 18* at idle. I'm going to bump mine up and maybe clean up the exhaust fumes...they are killing me!

At my 28 degrees the engine seems to start like **** after its been warmed up.

have timing below 550 rpm at 12 degrees or so, your starter is being overworked with too much timing during cranking when hot and that should fix your problem. Then ramp it back up to 28 degrees at idle like you had it.

use the vacuum advance feature to add in ignition timing to clean up your idle, have your basic timing at 15-18 deg to let it start easy, then add in say 10deg more using vacuum advance once its running, which makes it nice and clean idling

i start around 30, ramp up for cruise to around 34, but i run boost with a map sensor, so i ramp down to 20 under full boost
one thing i noticed with the Edelbrock intake, the engine wants a good shot of fuel off idle-the engine seemed a little lazy to me, as i open the throttle, i pushed down on the acel. pump at the same time, was much crisper-i switched from the pink cam to the green one, #1 hole, made all the diff in the world

When its warmed up it turns over fast it just takes a while to fire.

I need to check mine, but the current setup i have fires up instantly when cold or warm. No prolonged cranking or delay.

I have mine at 16-0rpms ramping up to 32-1400 ramping up to 36-3400 ramping up to 39-5000 then straight across from there on to 7000. Fires right up runs great and still on pump gas LS1 decked heads 40thou. going to tune it on the dyno this wed. It is running the same times now on pump gas as it did before with 34coming in at 1600 straight across to 7000 with 110 which i think was to much octane we are going to tune it on 103

39? Holy hell.

yep when we get it back on the dyno this wed i'm hoping to see if i can go to 40 with the 103 race gas. I know i've not experienced any knock at the settings i have now, Times were improved at the track as well I was running 113 in it to be safe till we got it on a dyno but decided to run 93 in it one night drove it to the track thought what the hell if it blows up then i can get serious right..lol But i was only 2 tenths off what my times were with running 34* with 113 i had ran 6.90 @ 100.1 i played with the timing with the 93 that night at the track and it was hot that night 88 out the times before it was low 60's out. I had ran a 7.10 first pass was like wow played with the timing curve and managed to get a matching 6.90 @ 101.6 out of it on pump gas and a way hotter night

I might have to experiment with more top end timing???????

Yea, i would like to get the highest timing possible for peak power, but i only have the ability to listen to detonation, dont know if i like that.

I'll let you guys know what i end up at after i get down with it wed on the dyno. I'm hoping to see some decent numbers out of it. Last time we just strapped it down during a dyno day event cause the people wanted to see it and just made a single pull on pump gas and it made 385 to the wheels running really really fat and only 34* that's also through a TH400 big driveshaft ford 9in. with 5.13 gears that really kill hp numbers on a dyno and drag radials. I am going to change the gears to either 4.30's or 4.10's so i can spray it. Things happen way to fast with the 5.13's in it right now for nitrous..lol

Trying to get all the carbed base info i can here, fixing to go to be after a 13 Hr shift and just want to get what i can done before work this evening.

Stock vs mod motor is the difference here anything above 36 degrees is to much for a stock motor my opinion. Someone wanna prove me wrong so i can copy ur curve and make my car faster

mildly joking, but not kidding about experimenting. I beleive low compression engines will allow more timing than higher compression engines. mine has 9.6:1 and I run 36*. I will experiment with more, carefully, watching plugs for signs of deto.
If your motor is 10.5 or better, I dont think more timing will help, but test,test, test, its the only way to know.

True man, i need to get some tires that will slip a bit but still hook so i can tune, i dont want to destroy my fresh T56 or snap a DS experimenting.
