With my real hot L18 with 300 degree @0.05" and .65 total valvelift cam which with 45mm webers & 36 chokes starts make real power from about 6500rpm idles quite nicely at 1000 rpm and runs very smoothly 1000-3000rpm but only with about 35 degree ignition advance. Any less and that engine dies when you hit the gas pedal. Actually best results come with 40 degree advance at 2000rpm, but that engine starts to ping at 6500rpm when it goes to power zone, so wihout computer based ignition max advance have to limit to about 35deg, with 25 deg initial advance and all mechanical advance coming before 2000rpm.
Also with wild cam that vacuum advancer have to removed as it's usually makes ignition unstable at low rpm when accelerating, resulting engine stuttering and poor running.
That L18 of mine won't produce much power under 4000rpm, it feels like having A10 under the hood and it also dies if push gas pedal too much at low rpms, but it still runs very fine, no problems at all with cruising in town at 1500-2500 rpm.
