Gots few passes on the old Hemi this year, and it still seems a little lazy at the hit...When do you guys decide to try it and why? Do I need a start retard?

I dont like to lock them out unless you keep advancing
the timing to have it idle right and that point is
in the 25* area... then its less than 10* of total
advance... I like to curve the dist so it starts nice
and advances to its total at about 1500-1800rpm
EDIT
you just dont want the start of the advance point
to be at the same rpm that you idle at.. that will
cause hassles when trying to get it to idle

Does the compression or fuel you run have a bearing on this?My cam is 262/274 @ .050 and I run 94 oct pump fuel,does this make a difference?I am having a bit of an issue getting a clean idle and starting it.

Whats your set up now... the dist in my Rampage is
locked at 40* right now and when its warn its a bit
to much... that dist we put in it on the dyno but I
am changing it to use advance (this is on a 416)..
the cam is 260/270 and was running 93 octane with
10.6 compression... higher compression does have a
effect on it.. the more compression the more it wants
to kick back

I am only giving it 14 deg at idle/32 deg total.I want to keep the timing down a bit,my last build showed signs of detonation.I run an MSD pro billet dizzy with the largest bushing and the lightest spring.18 degree swing with the black bushing.The cam is installed at 104 cl .

---

Thats low base timing for a cam that big... I would
think you would be closer to 20* base and limit the
total to what you need

Bob, that's a lot of cam with pump gas compression. My old 446 started and ran fine with a 264@.050 solid and i locked the distributor out and timed it at 35*.

Same deal with the 572 i have in there now ; pump gas compression and big solid roller. Starts and idles fine...even warm with the dizzy locked out at 35*

As long as it doesn't kick back i'd say lock it out

Some run the starter without ignition, and then switch on, after the starter got the engine cranking.
Next step that will get the timing rock steady, would be crank trigger.
