some major help needed!

Alright I have a sputter in my duster that dad and I just can't figure out.  We've changed motors, converters, ignition systems, distributor, carburetors, We were running 112 from Sunoco, but we put 92 pump gas in and the sputter went away.  The motor is a .30 over with 533 cam, Little head work, eddy intake and Holley 750 carb, anyone know of a site that'll give you the needed jet sizes for a particular set up?

do you have enough initial timing & have the timing curve shortened so it doesn`t overadvance

[Moparstud440]

timing is set at 35 degrees

timing is set at 35 degrees

That's fine....but what is the base timing (at idle).
