christer,the idle is set at 900 rpm. which is very low but the guy that set up the tune said it was right for the motor on how the timing was set.
all i can say is that the factory 6 pack set up does take awhile to warm up after start up,about 3 to 5 minutes. but when it gets warmed up it pretty much stays there the way you here it on my video. it does not change even if i put it in nuetral at a red light.
to start the motor it is a bit tough too and does take a few turns,but i am getting used to it and getting better each time by giving the motor much more gas as i turn the key. i have run into many hemi and 6 pack guys and they all say the same thing about start up. if its the stock set up (dual points with original distributor) it is a bit of a bitch in start up.
but let me tell you,when i start it at a cruise in, i get about 30 to 40 guys around the car just stareing at the shaker bubble as it just shakes perfectly at 900 rpm's.
forgot to mention that after the car is warmed up it does start a lot quiker. usually 1 to 2 turns.
"I have learned that all three carbs have an idle circuit, right?"
christer i am not sure about this,i heard everything pretty much runs on the middle carb and the other two are mechanical?
"383 with 6 pack",i never heard of this package,was there an original set up like that?
6 packs are very tough to set up and thats why i got a pro to do it for me but when it runs right Look out,it will give the Hemi a run for its money or even beat it.
