Thanks people, I'm going to set it at 8 deg and try it from there. I have 2
eproms 1 from a 5.0 and another from a 5.7, going to try the 5.7 cal 1st.
I get the cal codes next trip out to the shop.

If your refering to the gm data, that is for a mech distributor/carb..
His mention was TBI, and all the 5.7 stuff I recall is 6d, but found from
personal
experience some like the 8-10.
On a mech dist.'d engine the initial is a lot harder to have right since
it's hard to get the curve to kick in at idle, to get 16ish at 800 (and
lots
of motors would like 20)..
Now getting the curve right using a look up table is a no brainer, the
initial cranking/prime shoot has alot to do with the initial timing. With
6
the engine
(specially with a bigger than oem cam) it likes to windmill as it spins,
rather then hit and start. I perfer the instant crank and fire, but then
I
sometimes use a defeat switch so that in cold weather I can crank the
engine
to get Oill Pressure before appling fuel/spark.
